NARRATOR: Giza, 2014.
Large scale construction projects and high rise
developments encroach ever closer to the Sphinx
and the Great Pyramids.
Some believe that if the development continues
unchecked, it will lead to the destruction
of possible archaeological treasures
still buried near the complex.
But others feel that it may actually force the unearthing
of something more profound--
a twin Sphinx.
Everything in ancient Egyptian art is very symmetrical.
There's always two of everything.
When we see huge, big statues, there's
always two colossal statues.
There's always symmetry-- two statues guarding one road.
With a Sphinx we've only found one.
Some people believe there's another one.
There are actually many reasons to believe
it may have had a mate.
When we look at the Stele, the new kingdom
Stele between the paws of the Sphinx, in fact
it shows not one Sphinx, but two Sphinxes.
GIORGIO TSOUKALOS: There were long periods of time
where the Sphinx was not seen.
It was completely covered in sand.
And so the idea would imply that maybe
there are other structures that are still underneath the sand.
Is it possible that a second Sphinx
exists on the Giza Plateau?
NARRATOR: Although most researchers
are open to the idea of a second guardian on the Giza Plateau,
multiple theories exist as to where this Sphinx may be.
According to the Amduat, the ancient Egyptian funerary text
describing the hourly journey of the King in the afterlife,
there is said to exist a second Sphinx that faces to the west.
The fifth [inaudible] which seems to represent the Giza
Necropolis, by the way, is protected by one Sphinx
in the east, which is the existing Sphinx,
but they also show another Sphinx in the back.
Now, physically was there another one?
It's quite possible.
There is certain mounds that haven't been properly
excavated on the west side, and there
may be the remains of a Sphinx.
There certainly isn't a whole Sphinx.
We would have seen it by now.
But there may be the foundations of a Sphinx.
JONATHAN YOUNG: The non-existent Sphinx is almost as interesting
as the one we can look at.
Does that location have any special energy to it?
Is there some reason why life, faith, the gods,
would have it disappear?
NARRATOR: Could there really be a second Sphinx located
somewhere on the Giza Plateau?
And if so, how has it remained undiscovered
for thousands of years?
WILLIAM HENRY: We know less than 30%
of what's actually underneath the sand,
especially around the Giza Plateau.
So this is one of the exciting things about studying
and researching ancient Egypt is this idea that maybe you'll
be able to stumble into these ultimate secrets
that the ancients assured us are there.
NARRATOR: Would locating a second Sphinx
bring us closer to actually solving the mystery
of the Giza Plateau?
And if so, what might the consequences
be if this information is ever uncovered?
WILLIAM HENRY: If we put all the pieces together,
it suggests that the Sphinx is a repository
for this knowledge about how to actually use the Great Pyramid.
And once we do that, we're talking about the ability
to resurrect ourselves as celestial beings or star beings
and joining the extraterrestrials
who had a hand in building this incredible complex.
ROBERT BAUVAL: I very much believe
that the whole thing is a kind of cipher,
and I'll go to my grave on this one.
I've worked for 25 years to decipher
this cipher using astronomy, using the texts, and it reads--
I have under me the knowledge of our genesis.
JONATHAN YOUNG: Whatever it is we figure out,
whatever we discover when we get there,
it's not going to look like we thought it would look.
NARRATOR: Is the Sphinx the ultimate proof
that extraterrestrials were here on Earth in the ancient past?
And if so, might there be clues hidden
within this monolithic statue that not only reveal the truth
about our history, but why we are here
and how we can finally reconnect with our alien ancestors?
