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 archeology
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 archeology,
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 archeology,
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 archeology
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 China's Mysterious Cave Labyrinth.
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?
