NARRATOR:
Enormous man-made caves. PAUL BAHN:
Nobody knows what on earth these things are. NARRATOR:
Unexplainable structures. LOGAN HAWKES: You ask them,
"How did you build these?" And they'll say,
"We didn't build this." NARRATOR:
And underwater discoveries that challenge everything
we know about the past. DAVID CHILDRESS:
That's amazing. I'm convinced.
Something's going on down there. NARRATOR: Is it possible
that an advanced civilization inhabited the earth
thousands of years ago? And if so, were they human or something out of this world? GIORGIO A. TSOUKALOS:
Extraterrestrials colonized Planet Earth thousands of years ago. The more we uncover, it will all point
in one direction. We are not the first. NARRATOR:
Since the dawn of civilization, mankind has credited
its origins to gods and other visitors
from the stars. What if it were true? Did extraterrestrial beings really help
to shape our history? And if so... what might we learn
from the study of aliens BC? NARRATOR:
Traverse City, Michigan. May 22, 2015. At an undisclosed location in Traverse Bay
on Lake Michigan, author and explorer
David Childress has teamed up with
sonar technician Brian Abbott and underwater photographer
Chris Doyal to investigate
a series of strange underwater rock alignments they first discovered in 2007. So you don't bring very many
people out here, do you? No, you're one of the first
we've brought out to this site. We try and keep it
kind of quiet and secret. Chris has been out here
a few times. Well, it's a pretty
sensitive site, so we try to keep traffic
to a minimum. Well, how did you find
this site, anyway? Uh, we were actually
out looking for shipwrecks and we put our sonar
down off the side and I started to see stones
line up on my rose compass. Okay, and then you deploy this
sonar and take a picture, huh? Yeah, we, uh, we can get
that done here real quick, we can deploy the sonar
off the side and, uh,
start getting some images and show you what
we've got on the screen. All right, great, let's do it. Excellent. When I first found these
on the computer screen, I started to laugh,
because it was like, this can't be true, and I jokingly said, "Hey, we have our own
Stonehenge underwater," and everyone, "Ha, ha, ha," and I started looking at it
farther and I'm going, "Wow. We might have something here." Set the cable here,
we'll be all set. So we'll take a look
at the computer screen. Okay? All right.
So the sonar's spinning around. So as you can see in this,
uh, deployment location, we have, we've got one, two,
three, four, five, six stones. And what's really interesting
about this is, these stones all measure
the same distance across. CHILDRESS: Yeah, this does look
like an artificial alignment-- this stone circle and then
this line of stones there. Yeah, that was unique to me, because as an engineer,
when I look at stuff that's square or rectangular
or circle in nature, it-it kind of makes it jump out,
because Mother Nature generally doesn't
do things like that. What I saw on the sonar looked a lot like stone circles and stone alignments
that I've seen in England, or Carnac in France, and it makes me wonder
what's going on here in Ancient North America. So have you actually,
uh, been down here in scuba equipment? No, I haven't, but Chris has. Yeah, we went down and I actually took
some still photographs of it and we noticed
on one of the stones there's some really interesting
carvings on the surface of it. Some people have even said that it appears
to resemble a mastodon. -Really?
-Really. -Wow. Can we go down there now
and see it? -Yeah, absolutely. NARRATOR:
Taking an underwater camera down to the mastodon rock, Chris Doyal will send up
a live feed to a monitor on the boat. As he descends, he's gonna pick
out the stone here. CHILDRESS:
Okay. What's that? ABBOTT:
That's the stone. CHILDRESS: Is-is this the stone
that has the carvings on it? Yes, it is.
So he's moving slowly in on it. So you can see the head,
right through there. There's a tusk. So we have one leg coming down. CHILDRESS: It does look like the
stone has been carved, and... -ABBOTT: Yeah. -Yeah, you can
see the legs and a trunk on it. Wow! That's amazing. -I'm...
-Yeah, it truly is. Yeah, I-I'm convinced. Uh, something's
going on down there. ABBOTT: Between 10,000
and 12,000 years ago, mastodons went extinct. So we've got a carving
on a rock formation at, you know, a depth of water that, uh, you know, probably
shouldn't be here, but is here. This rock is probably
made out of granite, which is very, very hard, and if you look up close
at these markings, you can see that these were made
by percussion marks. These weren't just scratched
into the surface, that each line
was individually pecked out. That rock looks like it has
a carving of a mastodon on it. And that would mean that
that carving was made before the extinction
of these mastodons. So you have to wonder what was going on here
in North America at the time of the last ice age. NARRATOR:
The carved image of a mastodon? An animal that has been extinct for over 10,000 years? But what is it doing
at the bottom of Lake Michigan? Could it really be part of an artificially created
rock formation, like Stonehenge in England? If so, it would have
to have been created before the end of the last ice
age, when the lake bed was dry-- over 12,000 years ago-- and that would contradict
the currently held belief that early humans
were not capable of erecting monumental
structures in North America, or anywhere else, at that time. You never know when something's
going to pop up that's going to totally change your whole view of a,
of a period or even of human development. One of the main trends
that I've noticed in archaeology is that the dates for things
tend to go back all the time; the earliest pottery in a place, the earliest arrival
of people in a place. They always turn out
to be earlier than we traditionally thought. ANDREW COLLINS: Today we know
that there was a monument on the site of Stonehenge
at least 10,000 years ago. And this is not speculation. The archaeologists
are saying this today. And the same thing
seems to be going on in other parts of the world. CHILDRESS:
New dating techniques done by geologists
on the Sphinx in Giza indicate that it was carved
before 10,000 BC. So more and more, as we make
new discoveries in archaeology, it's pushing mankind
and civilization back farther and farther. TSOUKALOS:
Earth has a much deeper prehistory than what we read
about in textbooks today. You can read that Puma Punku
or Tiahuanaco, for example, was built between
500 and 800 AD. Some archaeologists
have suggested that Puma Punku and Tiahuanaco might date back
as far as 12,000 years BC, so around 14,000 years ago. NARRATOR:
Could it be that a sophisticated culture
existed on Earth thousands and even tens
of thousands of years ago? But if so, who built it? What happened to it? And might there still
be remnants of it, standing boldly,
right before our eyes? According to ancient
astronaut theorists, many of the answers can be found
by looking no further than the Old Testament
of the Bible. NARRATOR:
Throughout the world, there are incredible
man-made structures that have been found to date
back thousands of years earlier than archaeologists
initially thought. Is it possible that an advanced
civilization really existed on Earth
in mankind's prehistory? A close examination
of the so-called "Old Testament" of the Judeo-Christian
Bible suggests that although Adam and Eve are presumably the first humans
created by God, their son Cain later went on to marry and join
a thriving community. REVEREND LIONEL FANTHORPE: There
are a number of biblical stories which make us suspect that perhaps Homo sapiens were
not the only species on Earth or even the first ones. Although Adam and Eve
are recorded in the Garden of Eden
as the first human parents that when Cain went on his way after murdering
his brother, Abel, he comes to another city
with other beings living in it. Now, who are they? What are they? NARRATOR: According to ancient
astronaut theorists, several ancient texts can be
found that describe beings that dwelled upon the earth
before the time of Adam and Eve. These are often referred to
as the "pre-Adamites." There is a long
and ancient history of what today
are called pre-Adamites. Now, who are they
and what are they? This is a subject, of course,
of many legends. Those legends tell us
tremendous amount of things. People's lives extended
for thousands of years. They allegedly reached
high levels of technology, even traveling to the stars, and yet somehow something went
wrong in their civilization. The pre-Adamic
civilization fell, but some went to the stars, and they were told,
ordered by God, to watch and to observe. Well, let's assume for a moment that we had this incredible
planet, and, all of a sudden, the extraterrestrials,
other beings, came here, and they had their own
facilities, their own monuments, their own communities
for at least some time. And then, somewhere along
the line, they took off. NARRATOR:
Stories of a time when otherworldly beings
occupied the planet can be found in nearly all world mythologies. For the ancient Egyptians, the dawn of life on Earth
is referred to as "Zep Tepi," "the first time," when the god Osiris served
as an earthly ruler. The ancient Greeks called
this period the "Golden Age," when the Titans and
the Olympians dwelled on Earth. And the ancient Sumerian
accounts detail a time before the creation of man when the gods were the sole
occupants of the planet. The basic suggestion is
that extraterrestrials colonized Planet Earth thousands
of years ago, and we're talking not 10,000
or 15,000 years ago, but hundreds of thousands
of years ago. NARRATOR: But if an advanced,
possibly extraterrestrial, civilization really did
exist here on Earth, why is there no record of it? No apparent archaeological
or architectural evidence? BAHN: For most of the cultures
studied by archaeology, we are bereft of probably the vast majority
of what they produced. This is particularly true the
further back in time you go, simply because anything organic
will-will not survive. TSOUKALOS: The reason why most
of the ancient monuments were built by using stone
is because stone lasts forever. That's it. And the reason why we have
these monuments today is because they were
calling cards. They were calling cards
of a pre-civilization. NARRATOR: Mechanical engineers,
like Nikhil Kar, study the deterioration, corrosion
and decomposition of various materials to
determine the approximate rate of decay and structural failure. By applying these principles
to a cityscape, scientists are able to determine roughly how long it would take
the hallmarks of a sophisticated civilization
to disappear. If civilization was abandoned,
after 50 years, you would start to see, um,
material degradation processes take over for a skyscraper,
for example, would see parts of the external
facade crumbling to the ground. For steel material, you're gonna
start to see little pits form in that steel structure. After a thousand years, the soil
may begin to absorb the material and erode the material itself. Eventually, you're gonna
get to a point where only stone materials, natural stones are gonna be
around, such as Mount Rushmore. NARRATOR:
Quito, Ecuador. Here in the grasslands
of South America are the remnants
of the Great Incan Road. The sophisticated network
of pathways and trails covers over 25,000 miles
though Ecuador, Peru, Bolivia, Argentina and Chile. The Inca built this vast roadway without the use of the wheel,
draft animals, metal tools or even a written language. Yet modern engineers have noted that the roadway incorporates
advanced engineering principles. ED BARNHART: The Inca road
system was really one of the most magnificent ancient
architectural feats ever made. One of the things that made
the Inca roads so incredible is that they traversed
the Andes, these incredibly tall,
steep mountains. They had to bore tunnels
through mountains. They cut narrow paths
along sheer cliff faces. BRIEN FOERSTER: One
of the most intriguing things about the Inca road system
is that there is a major artery that goes from the northwest
to the southeast. And along that, we find almost every major
megalithic construction, including Tiahuanaco,
Puma Punku, Cuzco, Machu Picchu, Ollantaytambo and Saksaywaman. Many are starting to believe
that these megalithic structures are thousands of years older
than the Inca, and therefore parts of the Inca
road system are, as well, thousands of years older
than that civilization. The Incas, so many
of their great structures-- Cuzco and their royal highway-- you ask them, "Who built these?
How did you build these?" And they'll say,
"We didn't build this." Well, who did build it? CHILDRESS:
The Incas had elaborate legends of coming through
tunnel systems in the earth, appearing on an island
in Lake Titicaca, and then coming to Cuzco and finding already a-a system of tunnels and-and ancient mines
and structures. It was home of the gods. It's where they lived
before they left. NARRATOR: Is it possible
that the foundations of the Inca superhighway and the megalithic sites
along it are remnants of an extraterrestrial
civilization that once colonized Earth? According to ancient
astronaut theorists, the answer is a profound yes. And to prove it,
they point to a series of stone carvings
said to depict mankind's ancient ancestors. NARRATOR:
Southeastern Turkey. Buried beneath 20 feet of sand, archaeologists unearth the world's
oldest temple complex-- Gobekli Tepe. Radiocarbon dating suggests that the site dates back to at least
the tenth century BC, a time before the end
of the last ice age and 6,000 years
before prehistoric man was said to have
developed language. BAHN:
Gobekli Tepe is really one of the greatest archaeological
discoveries of all time. There are very few finds
in archaeology that really changed the whole
way we look at the past. And that is essentially
what has happened, because our view
of hunter-gatherers, uh, has changed enormously. We now know they were capable
of coming together in large numbers with--
under presumably some kind of authority
to cooperate on massive projects such as Gobekli Tepe, which
involved bringing huge pieces of stone from quite
some distance away, carving it beautifully,
setting these pillars upright, and doing this
on a massive scale. The very first temples in
the world are at Gobekli Tepe. And-and this in many ways
changes everything, because here we have
the smoking gun of a lost civilization. It confirms to us absolutely that at the end
of the last ice age, there was high culture
existing in the world. There's no doubt in my mind
that there are question marks all around the ancient world. And Gobekli Tepe offers
such a giant question mark, because according
to mainstream science, we were sitting in caves,
munching on bananas. And clearly that isn't the case. NARRATOR: Although,
to date, archaeologists have only excavated
less than one acre of this 22-acre site, what they have found
is astounding. The remains of a complex
of buildings, massive walls and T-shaped stone formations, some nine to ten feet tall and weighing up to 50 tons. Many of the stone pillars
are covered with relief carvings of animals, reptiles and insects. Archaeologists have also found
figures at the site that appear to represent humans with strangely
stylized clothing. BAHN: We have no idea
what these humans represent. We suspect that these
are not just simple statues commemorating people. T-They could be gods.
They could be spirits. They could be ancestors,
something of that kind. NARRATOR:
But perhaps most intriguing is a life-size statue found just six miles away that has been dated
to the same period-- the Urfa Man. DAVID WILCOCK:
This looks like a person who has come from
an advanced civilization, who's wearing something that has
much more of a defined collar, possibly even some sort
of advanced space suit. What the heck is he doing there? His face looks strange,
he's bald, his head,
his eyes look weird. There's something unusual
about this guy, and that could be a clue
that leads us into the mystery of an antediluvian,
or pre-flood, civilization. NARRATOR: Is it possible
that the strange humanoid figure found near Gobekli Tepe actually represents
an extraterrestrial? A being from a lost civilization
that existed on Earth sometime before
the last ice age? If so, does it give credence to other ancient stories describing otherworldly
civilizations that once existed here on Earth? There is this recessed courtyard
in Tiahuanaco that has all these
different faces. These stones were found
underneath the soil, meaning that at some point,
some type of event happened that buried
these particular stones. Some have actually surmised that they represent some type
of a pre-flood civilization, that what we have here is,
in fact, a remnant that depicts
that society. All over the world,
we have giant statues and-and carvings
of people's faces and heads. Some of them
are giant colossal heads like the Olmec colossal heads. Others are the Easter Island
type statues, which are huge and depict people
who have elongated heads. They're cone heads, essentially. They were giants of yore
with godlike powers. In my mind, we would
call them extraterrestrials. In all of these places,
the locals are saying, "Yes, these are our ancestors. These are the people
who came before us." NARRATOR: Might our planet
really have been inhabited by alien visitors
tens of thousands of years ago? And might they have brought
with them advanced knowledge, incredible architecture and technology that virtually
vanished, without a trace-- save for a few stone carvings
and monuments? But why? What catastrophic event
might have happened on Earth that would have wiped out
everything that wasn't made of stone? Perhaps further evidence
can be found by examining a number of massive
man-made caves recently discovered in China. NARRATOR:
Zhejiang Province, China. June 1992. A local villager pumping water
out of a pond in Phoenix Hill uncovers a man-made cavern
with stairs... hallways... and massive
ten-story-tall pillars. The grotto is one in a series of 24 separate caverns, each with similar proportions and intricately carved walls, floors and ceilings. BAHN:
Nobody really knows what on earth these things are. There's no trace
of them having been occupied or being used for storage. Uh, certainly not for burials. There's no trace
of anything like that. TSOUKALOS: There's a Swiss
author by the name of Luc Burgin who was the first to take
this story outside of China in his book<i> China's
Mysterious Cave Labyrinth.</i> And what he showed me
convinced me that some kind of advanced technology
was used here. It's one of the most
amazing things I've ever seen, where you enter
this subterranean world that clearly has been
hewn out of the bedrock with artificial means. It's almost as if there was some
sort of artificial mechanism that was grinding and drilling
all of the stone out, and this suggests
the possibility that they may have had some sort of technology. NARRATOR:
Archaeologists estimate that the material
excavated from the site would amount to nearly
one million cubic meters-- approximately the volume of 400 Olympic-sized pools. Yet there is no evidence of where this material
would have gone. And Chinese officials
have calculated that an endeavor of this
magnitude would take a minimum of 1,000 men working
day and night for at least five years. There is
no historical record, uh, of these caverns
having been excavated. So there's
no document explaining what they were used for, who excavated them. And this remains a very,
very, uh, frustrating detail for historians. COLLINS:
We know that in China there are written records
that go back at least 3,000 years. They make absolutely
no mention of these caves. So we must look
much further back in time for their origin. But exactly how old are they? Are they 4,000 years,
5,000 years? Are they even 10,000 years? We just don't know at this time. TSOUKALOS:
Some have suggested that they're
up to 15,000 years old. In fact, Chinese scholars
are the ones who have proposed that this cave system dates back to one of China's
first emperors, Huang Di. And Huang Di, as we all know, descended from the sky
in nothing else but a fiery dragon. WILCOCK:
Somebody went to an extreme amount of trouble to build
an underground civilization. Why would they do that? Is it possible that something
was happening on the surface of the Earth? When we go back
to the Icelandic legends, we see this cataclysm that is described as a cataclysm
of fire called the Ragnarok in which you have flames
in the air and rocks and gravel raining down from the sky. NARRATOR: In the Icelandic
Ragnarok legend, the world is turned upside down. A great fire is
followed by a submersion of the world in water, resulting in the death
of the Nordic gods and their offspring. Only two humans are left to repopulate the earth. It is a tale much like
that of the Great Flood found in the Judeo-Christian Bible. And similar stories
of a great deluge-- one that marks
the end of an old world and the start of a new one--
can be found in the histories of virtually
every ancient civilization on our planet. ROBERT SCHOCH: Virtually every
culture, every ancient culture talks about floods
and ancient floods. Some people dismiss this as,
you know, myth without explanation. But what we find
geologically is, in fact, we would expect flood legends. NARRATOR: In 2007,
a consortium of geologists publishes
its collective findings indicating evidence of a major meteor event. What they discover
is a carbon-rich layer in the geological record
at various sites across the globe dating back to around 10,900 BC. A separate study
conducted by scientists studying Arctic ice core samples
finds evidence suggesting a rapid glacial melt at nearly the same time period. SCHOCH:
The Ice Age ends very, very dramatically,
almost literally overnight. You see this in the ice cores. All of a sudden,
there are dramatic changes, temperatures rising, torrential rains, flooding. NARRATOR: Could
the geological record suggest that the stories
of a global cataclysm are true? If so, might the stories
of a cleansing of the earth of otherworldly beings,
leaving only humans to repopulate the planet,
also be true? Ancient astronaut theorists
say yes and suggest further evidence
exists in the tales of a long lost continent. NARRATOR:
Minneapolis, Minnesota. Here at the Minnesota
Historical Society are housed boxes upon boxes of notes, letters and research material
detailing evidence of an antediluvian,
or pre-flood, civilization. The collection
is the culmination of an exhaustive search
for proof of a prehistoric civilization, conducted by
the 19th century U.S. senator Ignatius Donnelly. COLLINS: Ignatius Donnelly
was a very interesting person. He was a U.S. congressman. Um, he was a writer. He was a-a cryptologist. And in 1882 he came out with his most famous book... What he did was
to propose the existence of a mother civilization, a-a lost civilization
that existed at the time of the last ice age. CHILDRESS: Ignatius Donnelly was
fascinated by the story of a lost civilization
that was destroyed over 10,000 years ago. He looked into all kinds of scientific anomalies
at the time, including the extinction
of mammoths and other animals. Stories of a civilization
within the Americas and in the Atlantic. NARRATOR: In his writings,
Donnelly concluded that not only did a lost
civilization actually exist, but that it was destroyed
due to a meteoric-type event that shifted the earth's axis in the distant past. Donnelly believed that remnants
of this civilization could be found
in the Americas... and the ultimate evidence
would be located underwater in the Caribbean. He was convinced that when Christopher Columbus
sailed west from Spain in 1492, he knew this as well. COLLINS: The explorer
Christopher Columbus, before his epic journey
to the New World, was very much aware of the
stories of a lost civilization. It was something
that was discussed in the various European cults
at this time. Ancient mariners,
the voyagers of the past, had maps which showed
different areas of the earth, which they could not know
anything possibly about because they hadn't been
discovered at that time, and were probably accessible to people like
Christopher Columbus, before his journey
to the New World. There were legends
in the Middle Ages that there was a land and a continent
across the Atlantic. And early maps started showing-- before Columbus, even-- a large island in the Atlantic, which they called Antillia. Columbus, on his first journey
to the New World, as he neared the Caribbean, he started seeing
weird lights in the sky. So you have to wonder: were extraterrestrials purposely trying
to help Columbus? Perhaps some of the knowledge
that he had of maps, and that he was really going
to find land across this ocean, had been assured to him. NARRATOR:
Could Columbus have been purposely guided to this area not only by ancient maps
of unknown origin, but also
by extraterrestrial beings? Although the secret
maps and charts of Christopher Columbus
have been lost, scholars attribute them
as having been a key source in the creation of one of
history's most enigmatic maps. The Piri Reis map
has been dated to 1513 AD, but what it illustrates
suggests geological knowledge that was unknown
until our modern age. ERICH VON DANIKEN:
A Turkish seaman, an admiral, painted the map. His name was Piri Reis. Now, if you see the map, you see the coastline
of the southern part of France. Then you see Spain. Then you see
what is today's Gibraltar. Then you see a part of Africa. On the other side, you see
a coastline of South America, but what is important, on the bottom
of the map of Piri Reis you see the coastline
of Antarctica. Now, this coastline is covered
today with ice and snow. So somebody must have mapped
this before the Ice Age. NARRATOR:
The continent of Antarctica was discovered in 1820, over 300 years
after Piri Reis drew his map. And scientists have proposed
that the Antarctic coastline has been obscured by ice for at least 6,000 years. Could it be that the original
source for the maps of Columbus and the Piri Reis map
predates our recorded history? If so, has evidence
been left behind on Earth to assure that we can piece
together the truth about a lost civilization? Ancient astronaut theorists
say yes and claim further proof
may be found underwater in the Bahamas. NARRATOR:
Andros Island, the Bahamas. 2003. Members of the Association for Research and Enlightenment conduct aerial searches
for underwater structures that might reveal evidence
of a lost civilization. Off of the coast of Andros, they discovered an incredible platform
of rectangular and square stones that stretched for several hundred yards. And all the indications are that it goes back
to the end of the last ice age and is probably around
11,000 to 12,000 years old. NARRATOR: The search is part of
a long-term project working in conjunction
with the Cayce Foundation. Their quest is
to locate remnants of the lost continent
of Atlantis, which healer
and psychic Edgar Cayce said would be located
in the area. WILCOCK: Edgar Cayce is arguably
America's greatest psychic. He was born in 1877,
died in 1945, and he has documented over 14,000 psychic readings. What's interesting is that Cayce also got into things
like reincarnation. Some of Cayce's clients were
told that they had lifetimes in the so-called mythical
civilization of Atlantis. In fact, Cayce's reading said that the people of Atlantis,
as a whole, had mass reincarnated
as the people of America and that America was,
in a sense, a future-life carryover
of Atlantis. NARRATOR: Cayce revealed
in his psychic readings that the truth about the nature
of this lost civilization exists in a hidden
hall of records at three locations
across the globe: in Egypt near the Sphinx, underwater in the Bahamas, and in the Yucatán Peninsula. Any three of these areas
apparently would have all of the records
that we would need to completely
rebuild our history and understand
how there may have been much more widespread extraterrestrial presence
here on Earth. NARRATOR: Could recent
archaeological finds in the Bahamas confirm
that Edgar Cayce was right about the existence of a lost
extraterrestrial civilization? And if so,
should we be concerned about his predictions
for the future of humanity? Cayce was a cataclysmist, and in his readings,
he was constantly talking about Earth changes
and pole shifts that caused civilizations
to be destroyed in ancient times. And Cayce said that we were
gonna have another pole shift around the time
of the millennium. Even a relatively
small asteroid, coming in at the right angle-- not necessarily hitting Earth,
but sort of grazing the earth-- could, theoretically,
change the tilt axis of the earth significantly. Now, if that occurred, land and ocean would
redistribute on the earth. WILLIAM HENRY: It seems
as if history repeats itself. And it may be that
at this moment, we are exactly
in the same situation that the citizens
of Atlantis were in. COLLINS: Perhaps we will find
out exactly what had happened to this lost civilization and learn from their mistakes and not sink
into oblivion ourselves. TSOUKALOS:
The more we uncover, it will all point
in one direction. We are not the first
and we never have been. An extraterrestrial
pre-civilization existed before our recorded history, and this truth will be revealed within our lifetime. NARRATOR:
Could the stories of a time when gods
and otherworldly beings inhabited the earth
be more than just mythology? And might the discovery
of unexplainable remnants from this lost civilization
reveal the truth about our
extraterrestrial origins, as ancient astronaut
theorists suggest? Perhaps we are on the verge
of uncovering the final piece of the puzzle that will change
our understanding of Earth's history forever. But will we uncover it before it's too late? CAPTIONING PROVIDED BY
