earth our home planet the only place in the universe known to support life yet could life-forms from outer space already have paid us a visit could they even be abducting members of the human race it may seem like science fiction but has Planet Earth already had a close encounter stories of close encounters with alien life are part of our culture every year in the US there are thousands of reported sightings of UFOs unidentified flying objects and some people even claim to have been abducted by aliens I am a perfectly normal individual that's had rather extraordinary odd experiences my entire lifetime natural phenomena or even military activities can explain most of the UFO incidents but some still keep people guessing there's no way that it was balloons or an aircraft or helicopters or flares people actually saw a mile to two mile wide craft skeptics argue that such sightings and Close Encounters are merely figments of our imagination perhaps inspired by science fiction movies and popular culture you have a dream about an alien in the middle of the night what is your alien going to look like your alien is going to look like my alien the alien we we both saw on television although even respected scientists admit that real aliens could have the capability to travel vast distances across the cosmos to visit earth there is no law of physics preventing a civilization perhaps a million years more advanced than ours from reaching the planet Earth some believe that there is overwhelming evidence that aliens have visited us possibly on many occasions throughout history leaving artifacts and messages ranging from crop circles to the pyramids I saw some strange objects and strange lights I saw some things I couldn't explain they were definitely under intelligent control for those of you that are skeptical I would ask that you look at all the incidents there are some very serious things out there some incident really needs an investigation in 1995 dr. Lynn kite I saw lights she could not explain near her home in the mountains just north of Phoenix Arizona she had her camera with her I really concentrated on that top orb that was starting to disappear it didn't budge it just slowly doomed as if once it disappeared it was still there and I noticed an eerie silence as if time had stopped it was just extraordinary very strange two years later on March 13 1997 kite I was also among the thousands of witnesses who shared a remarkable experience thousands of people statewide were looking up purposely to the sky on a clear beautiful night to catch a glimpse of the hale-bopp comet when this mile to two mile wide triangle craft traversed the entire state I mean it really went through the most populated corridor of Arizona totally totally silent this was a massive parade throughout the state some people find it hard to dismiss the Phoenix lights case because there were so many eyewitnesses after a brief investigation the military revealed that the lights were created by flares released from a squadron of aircraft flying in a V formation despite this explanation some people maintained that the lights were otherworldly pyrotechnic expert Paul Mann has worked with flares for over 23 years he believes that staging this event would be incredibly challenging I think you would find it very difficult it's a mistake a flare for or people would regard as a UFO although he won't be launching the flares from a fighter jet Paul believes that he can explain the difference between flares and the Phoenix lights here are flesh which will go to about 300 feet high give you a constant burn but you'll see there's a slight flicker in it anybody would be able to spot that's a flare rather than the craft so we've got a shimmering red light there lots of smoke you can see the smoke trail the pinpoint of light will give it away as a flare and it falls to the ground it doesn't hover for hours so for anybody who saw the Phoenix lights just if it was a pyrotechnic that could last for so long that was quite an achievement and scaled it to hold in the sky was something else altogether I know what I saw and thousands of other people know what they saw and it definitely was not flares the characteristics are quite different from these orbs there's no smoke trails these are bulls these are orbs and are in rocks all informations the data speaks for itself some people believe that flares are an improbable explanation for the lights over Phoenix dr. Michael Shermer publisher of skeptic magazine thinks the incident highlights the difficulty of judging the truth about UFOs people are poor eyewitnesses all of us judging the size motion and speed of objects in the sky particularly at night or dusk it's very difficult to do Shermer has been writing about the unexplained for over 10 years he questions not only the quality of the evidence but also the reliability of human testimonies when somebody says oh it was 200 meters wide in the sky how do you know was it next to something that you knew the size of already and then you can judge it's twice as big as that no people just make wild ass guesses these wild guesses include mistaking military aircraft weather balloons flares and even the planet Venus as alien craft yet such sightings lead many people to believe in the existence of UFOs despite logical explanations from scientists and the US government ironically official denials of UFO landings may actually encourage a popular belief in their existence because of a fascination with conspiracy theories and a fear of government cover-ups particularly in the infamous case of Roswell Roswell this is the mecca of UF ology initially the story given that it was a weather balloon was a lie it was a lie because it was a national security secret it was a national security secret until 1995 when the government said that Roswell wasn't actually a high-altitude weather balloon but a high-altitude surveillance balloon to monitor Soviet nuclear tests this revelation only serves to convince the UFO community that the government are still covering up whatever did happen at Roswell so the u.s. ology people said ah hi you see we've been saying that they lie yeah right but they're saying what it actually is yeah but that's a lie no that makes perfect sense for a cold war atmosphere in 1947 the mystery surrounding Roswell has been fuelled by misinformation and the shifting official explanation that keeps the story alive yet sometimes even the military themselves spot the unusual in 1980 personnel at an Air Force Base on the east coast of England saw a strange light in a nearby forest deputy base commander Colonel Charles halt was on duty when he received a strange message from one of his staff when the on-duty police lieutenant came in and insisted on seeing myself from the base commander and talking to us privately he was white as a sheet the lieutenant reported that a strange unidentified flying object had been seen descending into nearby Rendlesham forest Colonel halt and a disaster preparedness officer visited the supposed landing site they recorded their mission as evidence all the birds got quiet all the animals in the forest were just silent we approached a site where they said this alleged craft had landed there were three indentations in the ground about an inch and a half to two inches deep about eight to ten inches across they were about six seventh maybe eight foot apart in a nice triangular shape being cautious Colonel halt and his disaster preparedness officer took radiation readings with their Geiger counter the levels were four times higher than normal then something moved in the trees a bright red light with a black center it was moving through the trees it appeared to be shedding something like molten metal almost like steel coming out of a crucible as we stood there in awe watching it it silently exploded and broke into multiple white objects who just disappeared many journalists and researchers claimed that what Colonel halt and others actually saw while in Rendlesham forest was in fact the lighthouse at nearby Orford ness but Colonel halt remains convinced that what he saw wasn't of this world I know what we saw but I don't know what it was my own personal suspicions are that there may have been a craft that was damaged injured or it may have been a reconnaissance vehicle of some type taking a look at all the activity in the area in January 1981 Colonel halt contacted the British Ministry of Defence never received an official response he is convinced that his close encounter was genuine and that government's cover-up this and other UFO cases dr. Michael Shermer is not so sure problem of government cover-ups like that is people can't keep their mouth shut if aliens were really here and the government was covering up surely some lower echelon person would say I've got the story of a lifetime even if governments were trying to cover up UFO incidents people haven't stopped questioning the official explanations either aliens exist or they don't either thought is frightening for any UFO to get here it would have to travel across space from another part of the universe light-years away where might they come from and just how would they get here has earth ever had a close encounter with an alien civilization there have been many supposed sightings of UFOs but no definitive evidence of a visit but whether or not aliens have dropped into our own backyard many scientists do believe that they could exist I would be shocked if we were alone it would be an incredible waste of space considering how many galaxies there are there should be lots of planets like ours with life on it the universe is about 14 billion years old and expanding at a phenomenal rate it holds billions and billions of stars far more stars than there are grains of sand on all the beaches on earth and some of these stars have planets orbitting there are plenty of places from which et could originate physicist Lawrence Krauss believes that the most likely place for et to call home would be on a planet similar to our own life seems to form ubiquitously relatively easily and conditions like this so we we would expect one simple way to find life would be to look for planets like Earth the problem is that any such planet is going to be a long long way from Earth outerspace distances are so vast they are measured in lightyears rather than miles one light-year is a distance of nearly 6 trillion miles that's the distance traveled in one year by a beam of light moving slightly in excess of 186,000 miles per second light from our own Sun reaches earth in about 8 minutes and takes another 10 and a half years to travel to the nearest known planet outside of our solar system any alien planning to visit us from this planet faces a round trip of over 120 trillion miles the only way to shorten the duration of such a journey may be to go faster than the fastest thing we know in the universe light itself in 1905 Einstein laid out special relativity and in that theory you cannot go faster than the speed of light there's a cop on the block in some sense that says you can't break the light barrier Einstein's theory of special relativity suggests that there is a cosmic speed limit preventing anything and any alien going faster than the speed of light however in 1916 Einstein created an even more powerful theory the general theory of relativity it opens up the possibility that instead of beating the laws of physics the answer might be to get around them theoretical physicist Michio Kaku believes that this holds the key to breaking the Lightspeed barrier space-time is a fabric a fabric that can be stretched and compressed and perhaps even ripped that might give you the possibility to break a light barrier Einstein's theory proposes that matter causes space-time to curve imagine a heavy ball on a rubber sheet the ball's presence causes the sheet to distort into a hollow if a smaller ball is then dropped onto the sheet it will spiral toward the heavier ball Einstein theorized that space like the rubber sheet is warped as objects travel through it and if space can be warped then there may be a novel way to travel from one side of the galaxy to the other if you have a sheet of paper a straight line is the shortest distance between two points however there's a loophole if you are to fold the sheet of paper then you realize the shortest distance between two points is actually a wormhole some scientists suggests that wormholes are space-time tubes which act as shortcuts connecting distant regions of space theoretically an alien using wormholes could travel between two parts of our galaxy faster than a beam of light could travel through normal space and time it's a shortcut first described more than 150 years ago by a mathematician in Oxford England that man was the author known as Lewis Carroll Alice's Looking Glass connects the countryside of Oxford to a fantastic world called Wonderland and if you were to put your hand through the looking-glass your hand would leave Oxford and go to the other side of forever that is a wormhole what we physicists call a multiply connected space wormholes may be the ideal transportation network but manipulating the laws of physics could bring catastrophic consequences you don't know how stable they are it may be quite radioactive there may be quantum Corrections and radiation as you enter the wormhole or perhaps it will close up even before you can enter it may be possible to artificially create a wormhole but it would take enormous energy and advances in technology way beyond our imagination to rip through the fabric of space and time but maybe there's an alien civilization so advanced that they can build these super galactic highways with ease intelligent aliens may also have found another trick to navigate around the universe perhaps they can actually move space itself as far as we know space can do whatever the heck it wants it can expand and response the presence of matter and energy if we could somehow harness that then in principle you might be able to develop something you might call a warp drive the alien craft would collapse the space in front of it and simultaneously expand the space behind it in that way the ship would transfer from one part of the galaxy to another without actually moving an inch it may sound like the stuff of science fiction but for some advanced aliens it could be science fact I can show you what this balloon I have a little replica I've drawn of the USS Enterprise from Star Trek and just so you know the local surroundings have the Sun here and have the moon Saturn and what I want to show you is it is that the the enterprise could travel away from this star system and towards this star without ever moving with respect to its local surroundings how can I do that or if I squeeze the balloon at this end then I expand this region of the balloon the distance between the the starship and these stars has increased but the starship hasn't moved at all with respect to its local surroundings and so what I've done is I've had space do the work nobody knows how a warp drive might be powered and Kraus believes that its use would be fraught with danger it may not be dangerous for the participants in the space craft but it'd be pretty dangerous for everyone else because when you can try space in front of you you literally crush everything between you and the nearest star when you expand space behind you you you put incredible tension and everything around you you'd have to have an interstellar highway where you cleared out everything in between because otherwise you'd destroy basically everything around you our own technology is nowhere near sidestepping the laws of physics but an alien civilization that has evolved a million years ahead of us might already have found a way earthbound physicists who are looking for life take this idea very seriously they have devised a system to categorize alien civilizations according to how advanced they may be when we physicists looking at a space we don't look for little green men we look for type 1 type 2 and type 3 civilizations a type 1 alien civilization would be so advanced it could harness all forms of energy on its planet including oceans volcanoes and even the weather they would soon exhaust the power of a planet and use the energy of their local star at this stage they would be categorized as a type two civilization eventually they become galactic they begin to colonize entire star systems they begin to have fantastic energies allowing them to manipulate stars and black holes that is type 3 perhaps a hundred thousand to a million years more advanced than our technology but where would our own civilization be on this scale we don't even rate on this scale we get our energy from dead plants oil and coal that's how primitive we are our official rating is type zero we cannot travel across the vastness of interstellar space however a type three civilization would have developed the technology needed to control space and time in order to travel freely throughout the universe you cannot rule out the possibility that an extraterrestrial civilization perhaps a million years more advanced than ours have the capability of reaching the planet Earth but any alien civilization developing ways of traveling across the galaxy to Planet Earth still faces potential disaster if they reach us at all than the oxygen in our atmosphere the very thing that keeps us alive may prove to be deadly poison for our alien visitors if an alien civilization has successfully learned how to control time and space and cross the interstellar void to visit earth they will face a serious danger our atmosphere it protects us from solar radiation but it's a dangerous barrier for any approaching spacecraft as an object approaches Earth from space it heats up due to friction with molecules in our atmosphere the heat burns up most objects such as asteroids before they reach the ground NASA spacecraft use this friction to slow down as they re-enter the atmosphere heat-resistant tiles protect them from the intense heat without them the ship would burn up but some physicists believe that a technologically advanced civilization would solve the problem long before they reach our atmosphere I would suspect that any intelligent creature with an advanced form of space travel was simply slowed down even before it reaches the planet Earth having navigated our atmosphere and landed safely on our planet the aliens face their next big hurdle it's unlikely they could just step out of their craft Earth's atmosphere would probably not match exactly the atmosphere on the home planet of a visiting alien in fact unless the aliens were adapted to oxygen they would find the gas extremely poisonous say aliens come to earth you wouldn't expect them to just walk out of their spacecraft and breathe the air and start eating apples and oranges here in the Mojave Desert in Nevada NASA's Space Science Division studies how Earth's basic organisms live in extreme environments from this they hope to ascertain how different species might survive potentially hazardous conditions leading the research is dr. Chris McKay and we take for granted that life needs oxygen and we all need it plants and animals need oxygen but we have developed very special machinery and enzymes for detoxifying oxygen oxygen is intrinsically poisonous but what evolution have happened in the same way on the home planet of an alien visitor would they have evolved to cope with oxygen in an extreme case the fundamental chemistry might be completely different with different gases dr. McKay studies samples that contain over 10 million bacteria they reveal that some species here exist using totally different principles - the vast majority of life on Earth if we look at the bacteria we get a glimpse of how strange chemistry really can be how these organisms can be really so so alien the strength of our Sun poses another problem for visiting aliens the energy from its rays supports life on Earth but it can be dangerous too much Sun can blind humans burn us or even cause cancer for a creature from another planet our sun's rays could be deadly you can imagine life-forms from another world coming here and find a UV light here to be stunningly bright and require extensive sun shields and sunglasses and other ways to protect themselves and then there is Earth's invisible hazard for aliens gravity a visitor from another planet might find Earth's gravity a challenge humans have grown up with it in bodies designed for one gee if we subject our own bodies to extreme gravity the consequences can be disastrous fighter pilots making extreme turns can experience forces as high as nine GS that means that a 160-pound pilot feels lucky weighs over 1500 pounds anything above nine G's the pressure becomes too great and the pilot will blackout aliens from a planet with less gravity would probably experience a similar effect say the Martians came to earth while on Mars the gravity is 1/3 on earth the gravity would be higher for them so even if they were fit by Martian standards they might find this high gravity a drag but it's not hard to postulate them have the technology to allow them to operate in higher gravity a far less predictable danger facing a visiting alien is germs just as in HG Wells is War of the Worlds simple bacteria might be deadly to visiting aliens the bacteria on one planet could have serious consequences for organisms on another planet now the Martians come they invade Earth they kill off the armies of Earth with no problem but then the bacteria on earth infect the Martians and kill them in the end earth wins the war of the world but not because of the prowess of human technology but because of the biochemical diversity of the bacteria history has shown that there is good reason for visitors from another world to be cautious and for us to be cautious about them when the Spanish invaded the Americas they brought a far deadlier weapon than their guns and swords they brought smallpox the flu and other illnesses when those barriers were reduced and life spread between the new world in the old world there was a lot of death and destruction as a result of we might contaminate visiting aliens or they might contaminate us this fear of infection from new species of bacteria also troubled NASA during the moon exploration of the 1960s they place the first astronauts returning from the moon in quarantine in case they carried deadly space germs michaei hopes that an alien civilization exploring the universe would also be careful not to contaminate planets with their bugs one would imagine that an alien civilization with the technology to move between worlds would have the sense to realize the same problem and have strict biological barriers and controls they wouldn't just land and go out for a picnic and spread out their stuff on another world it's clear that the occupants of an alien spacecraft traveling to earth would face a catalogue of dangers first they would have to survive the destructive forces within a wormhole then avoid burning up in the Earth's atmosphere and finally protect themselves from poisonous oxygen or deadly germs perhaps alien visitors would decide not to take the risk themselves what if they sent explorers who never aged and who never die from deadly diseases the most efficient way is with robots these are self-replicating nanobots nanobots are miniature robots minut and lightweight enough to be potentially invaluable in space travel one of the major factors in traveling fast through space is weight the smaller you are the faster you can go in fact subatomic particles can travel at near the speed of light so tiny nanobots may be the best way of exploring the universe scientists believe that it might be possible to create microscopic nanobots able to clone themselves these would land on moons and planets and self-replicate allowing an alien civilization to explore vast tracts of the galaxy without ever leaving their home planet eventually you would have a sphere of perhaps trillions of robots expanding near the speed of light landing on moons each robot creating other robots that's the most scientifically reasonable way to explore the galaxy that's how nature does it that's how viruses work humans are already exploring the cosmos using robots NASA's Voyager probes are heading deep into space sending back data as they go and robotic Rovers have explored the surface of other planets in our solar system but because of their size it appears that nanobots could be the most logical way to explore the universe but so far there is no evidence that alien nanobots have ever visited earth and even if they have will we be able to detect them the vast majority of people who claim to have had Close Encounters in fact describe not miniature robots but living alien creatures often none too friendly and prone to abducting probing and experimenting upon their victims an advanced alien civilization might be able to manipulate physics and cross time and space to visit earth but some scientists question why on earth would they want to they suggest that beings capable of traveling through space and time would be millions of years more advanced than humans and would find life on earth of little interest and even if they do want to make contact they might not be friendly based upon the human races own history of confrontation Michael Shermer publisher of skeptic magazine as his own theory if you go by what happens here on earth we would never want to come into contact with ET we would be eaten or enslaved or killed because that's what happens here so that's not good even so some people claim to have already had a close encounter with extraterrestrials some even claimed to have been abducted by them the alien abduction experience is a fascinating one these stories have all the earmarks of a very human kind of experience it's a type of night terror it's a bad dream because there is no evidence outlandish accounts of alien visitation are greeted with disbelief so most claimants are keen to conceal their identity one woman from New York who we have named Molly claims to have experienced repeated visitations throughout her life probably the most strangest and disturbing memory that I have is of a dream with a white Pau coming into my neck and placing a tiny little stick in it and when I woke up that morning I was very shocked to find a strange painful lump on my neck and when I felt it because I thought it was a pimple I discovered something hard in there the shape of a piece of rice according to Molly the tiny implant worked its way deep into her body and before she could get medical advice it disappeared without a trace another encounter that she vividly remembers actually involved being taken on board an alien spacecraft I recall being in I'm gonna call it a clamshell but it was more like a scallop and it had a top and a bottom and I can recall being inside of it in the top closed over you I experienced medical procedures with very strange types of devices one of the beings was very tall and very thin and very insect-like like most people who claim to have met aliens Molly has no evidence at all to back up her story and skeptics consider that experiences like hers are more to do with popular culture than extraterrestrials most people just give the default explanation that comes to mind which is whatever they've been seeing on television and reading in popular magazines and books over hundreds of years the phenomenon of visitations has manifested itself in a variety of guises in the Middle Ages people reported stories of angels and demons while a hundred years ago reports spoke of spirits and ghosts many scientists including Shermer believed that a combination of sci-fi stories movies and real-life exploration of space encourages people to manifest their fears in the form of alien visitations the aliens are are angels they are our demons that that's who we personify as these weird anomalies we call them aliens because that's what we're into we're in the Space Age in the age of science fiction however that does not completely explain what causes people to believe they have experienced a visitation dr. Michael Persinger from Laurentian University in Canada believes he has discovered a link between the alien visitation sensation and electromagnetic fields he suggests that fluctuations in electromagnetic activity could stimulate a reaction in the brains of certain individuals and account for most alien visitation experiences the experience of a presence occurring usually late at night and either producing a mystical experience or a sexual experience or even a terrifying experience shows up in all cultures and we now realize that this sensed presence is built into the human brain itself Persinger believes that it is possible to induce something like an alien visitation experience in almost anyone he does this by creating a complex electromagnetic field in his laboratory and applying it to people's brains to demonstrate Persinger and his assistant place a volunteer inside a soundproof chamber electrodes producing the magnetic field are attached to the subjects head then he is blindfolded and the lights are dimmed Persinger monitors his stats and waits for his subject to experience a feeling similar to that of an alien presence if you wish to report them aloud or in a head within minutes the electromagnetic fields trigger a shocking reaction in the subjects brain how he describes it is could be a function of his culture his experiences and his expects a lot feels like a dying at this point Persinger stops the experiment in this study the subject is visualizing the presence in a terrifying way I have never had any feeling that ever it just made me feel a little trapped and it hurt I don't know closest I've ever been to help do it just it was not the place to be the volunteer was extremely sensitive to the electromagnetic fields which stimulated his brain however this technique demonstrates the extraordinary power of our brain to turn our fears into monsters and demons and even aliens from distant worlds dozens of people who had experiences that they attributed to alien abductions and experiences when we put them to the chamber they have a very similar experience the terrifying experiences induced in the chamber are caused by channeled electromagnetic fields Persinger believes that abduction experiences in the real world are caused by electromagnetic fields created by natural phenomena such as Sun flares and seismic activity and changes in atmospheric conditions and it's thought that our common physiology and global culture is responsible for the similarity in the accounts inevitably we're all going to have similar experiences because our brains are wired that way we'll see the same kinds of illusions we'll have the same kinds of hallucinations and so on the role of electromagnetism in alien experiences is far from proven some researchers suggest that sleep paralysis or conditions like post-traumatic stress are to blame but until we've made contact with et we may never know if aliens are all in the mind or not and if et did reveal itself there could be another barrier to overcome language it may be that aliens don't choose to talk with us at all they may decide to talk to one of the other species that inhabits the earth and that could be whichever species they consider possesses the most intelligent language it may be possible for aliens to cross the interstellar void to land on earth and to adjust for survival in our atmosphere but communicating with us in any meaningful way may prove to be the hardest step of all we are arrogant to believe that they're gonna want to actually talk to us and visit us I mean why think of ants in an ant hill if someone is building a five laying superhighway right next to the ant hill with the ants know how to communicate with the workers the main danger is that these workers will simply pave over the ant hill and not even realize what they've done in San Francisco a few scientists are already studying ways of communicating should et ever come to call leading the hunt is SETI the search for extraterrestrial intelligence for the last 40 years SETI scientists have been monitoring the skies listening for messages from alien species SETI is just about every field you can imagine applied to the search for life in the universe SETI scientists Lawrence Doyle believes that the key to communicating with aliens is first to understand their level of intelligence and for that he needs to establish how organisms communicate there hasn't been a search for extraterrestrial intelligence yet there's only been a search for extraterrestrial technology we plan to make it a search for intelligence by understanding the laws that create communications that if we get signals we can tell it's a communication as opposed to random Astrophysical processes by understanding the laws that dictate communication Doyle can identify and separate real patterns of communication from random noise to do this he uses a mathematical equation known as information theory which was originally developed to quantify the amount of information sent down telephone lines Doyle uses it to analyze the complexity of a language he calculates the interdependencies of different words or sounds within the language the greater the number of words or sounds that can be strung together that are dependent on the first word or sound in the sequence the more complex the language on this scale English is a level 9 communication system Doyle now plans to use the same technique on alien communication and the higher the complexity the more superior the intelligence any alien or extraterrestrial message has to obey the rules of information theory there's no other way to transmit information and if we can measure how complex their communication is it may be an indicator of how complex an extraterrestrial society is but information theory can only help Doyle understand the complexity of an alien signal not the content so even if he spots ET he won't know what ET is saying it's the same problem we have on earth when humans try and communicate to other species if you smile at a wolf it does not mean I'm happy it means you want to pick a fight if you smile at chimpanzee it means you're scared so even a smile doesn't work how do you communicate with an alien is a tricky point we can't even agree on the same symbols of greeting among species on earth Doyle has been using information theory to discern patterns and rules in animal communication and study their complexity the results have been surprising with his current data Doyle has found that squirrel monkeys have a level 3 communication system while dolphins have a level 4 so who does Doyle think might be the best candidates to communicate with aliens so far he's not convinced that either dolphins or humans have the necessary linguistic skills but he has found a species on earth with a communication level much much higher humpback whales we're majoring in because they look like they will have the absolutely most complex communication system maybe on the planet Doyle study of humpbacks is in its early stages and so far he has only studied their social calls but it may be that when extraterrestrials talk to the earth species with the most intelligent language they won't talk with us they'll talk to humpback whales instead but despite listening to the universe for four decades said he has yet to discover a single confirmed extraterrestrial signal to actually find real aliens we may need to look in a different place a place closer to home perhaps we should take a closer look at ourselves when you look in the mirror perhaps you are looking at a Martian it's always amusing to me when I hear people talking about UFOs and aliens for me it's the bacteria there could be bacteria here that are really alien life on Earth could have come from Mars and we could all be aliens McKay and other scientists believe there's a chance that billions of years ago alien bacteria were blasted from the surface of another planet and carried away in a meteorite the meteorite might have eventually crash-landed on earth and spilling out the bacteria allowing it to grow and flourish it's a process called panspermia if panspermia is true you and I are aliens in the sense that our life did not develop on the planet that we're living now professor Jay Melosh of the University of Arizona has studied meteorites that have landed on earth to see if they could have transported life from other worlds this meteorite is a piece of Martian basalt where it came from was a large meteorite impacted on the surface of Mars it's almost an ideal delivery mechanism it's ideal because the rock protects the bacteria from radiation and extreme temperatures in space it would also protect it from the impact of crash landing on earth to test whether bacteria could travel safely through the cosmos Milosh and his colleague Wayne Nicholson conduct an extreme survival experiment they inject a large block of rock with bacteria and take the sample to the Ames vertical gun laboratory near San Francisco the blocks placed inside a large vacuum chamber and milosh then fires a projectile into it at over 13,000 miles per hour it absolutely destroyed the Rock target blasted into tiny fragments amazingly despite the rock being virtually vaporized the bacteria survived intact if they could survive it's not a big stretch to think that organisms on the surface of another planet could also survive meteorite impact and launch in the interplanetary space the experiment shows that bacteria could not only survive the vacuum of space but also the impact of landing on earth one theory is that bacteria from another world evolved over millions of years to form life as we know it so perhaps all life on our planet is alien in origin we human beings life plants animals everything we see descended from that common Martian ancestor that's a possibility we may go to Mars and suddenly see well that's where a great great great grandma with because of the vast size of our galaxy aliens even highly advanced ones may never have visited earth in spaceships all UFO sightings may well be no more than a simple misinterpretation of what we are seeing and alien visitations a product of our overactive imaginations but aliens might have been here all along we and all the species on our world could be the direct descendants of extraterrestrial life-forms in the strangest twist of all perhaps we are the aliens
