NARRATOR: December 20, 2013.
Noted ecologist Dr. Ellis Silver publishes his book
"Humans Are Not From Earth."
In it, he proposes that humans possess a multitude
of physical vulnerabilities, such as slower childhood
development, a heightened susceptibility to illness,
spinal problems, and difficulty giving birth.
He concludes that they most likely
evolved on another planet.
There are a lot of indications that mankind, the human race,
actually did not evolve on the planet Earth.
For one thing, if we go out in the sun too long,
we get sunburned.
And that doesn't make a lot of sense,
unless the conditions on planet Earth
have changed very dramatically in the last few thousand years.
You have to wear sunglasses outdoors.
That also indicates that our eyes are not
properly adapted to the planet.
Some recent studies in sports medicine
have shown us that the human body creates two types of fat.
One isn't a good type of fat, and the other one is.
And interestingly enough, studies
show that if you bring the temperature down to about
67 degrees Fahrenheit, you create the good fat and not
the bad fat.
Near the equator on Mars, in the summertime,
it's about 67 degrees Fahrenheit.
Now, that's Mars today, with very little atmosphere.
Imagine in the past, where Mars had an atmosphere.
The average temperature on the surface
might be around 67 degrees.
MIKE BARA: Another factor is that when astronauts actually
go into space, their circadian rhythms,
their body clocks, change from 24-hour
days to a 24.9-hour day.
And that happens to be the exact rotational period
of a single day on the planet Mars.
Given the fact that our body clocks are tuned to the planet
Mars, not to the planet Earth, that indicates to me that we
actually came here from there.
NARRATOR: While the notion that humans could have originated
on the lifeless, barren surface of Mars may sound far-fetched,
scientists are now certain that, in the distant past,
the red planet was once blue and boasting
a more robust atmosphere.
One of the most fantastic things that we've
discovered with our orbiters and our rovers on Mars
is about its history.
And a number of really spectacular surprises
have come out.
The first one is that Mars, at one time in its past,
looked more like the Earth.
It was a blue ocean world with a significant amount of water.
We know for a fact that, billions of years
ago, when we were first getting started here on Earth,
then Mars was a much more clement place.
We know that it had a thick atmosphere to shield
and blanket the planet.
And it would have had organic molecules, the building blocks
of all life as we know it.
So it stands to reason that maybe Mars had its own genesis,
its own origin of life.
NARRATOR: If the human species was genetically engineered
by extraterrestrials, as ancient astronaut theorists suggest,
is it possible that it was designed
for the environmental conditions of its original home on Mars?
And if so, what might have caused
our ancient ancestors to come to Earth so many years ago?
And at some point, billions of years ago, Mars,
it suffered a kind of environmental catastrophe.
Its atmosphere started bleeding away into outer space
because it had no magnetic field to help shield the planet.
Some have suggested that, at some point,
Mars had an atmosphere, and due to some cataclysmic events
on Mars, the Martians had to find a new home
within our solar system.
And they came to Earth.
So what if we are the Martians?
NARRATOR: In 1976, author and researcher Zacharias Hitchens
proposed that a 12th planet once existed
in our solar system, just beyond Mars,
that was somehow destroyed.
Although his declaration was based
on his study of ancient Sumerian texts,
it was largely dismissed by the academic community,
who thought the idea absurd.
But recent physical evidence has come
to light that may prove Hitchens more correct
than even he believed possible.
October 7, 2008.
An 80-ton asteroid enters the Earth's
atmosphere and explodes 23 miles above the Nubian
Desert in Sudan.
That day, an estimated 600 meteorites literally
showered the landscape.
But when examined, the meteorites
were found to contain something incredible--
diamonds.
They also contained something else--
evidence that they came from what scientists now
believe to have been a lost planet
in our solar system, one which was destroyed
thousands of years ago.
The asteroid belt in our solar system, it's a strange thing.
And some have suggested that these
are the remnants of a planet that exploded at some point.
And the inhabitants of that planet either went to Mars
or they came to Earth.
I am convinced that the reason why there
is such a huge fascination with space travel
is because that's where we come from.
