You know, there's a lot going for this documentary about one of the oldest an made structures on the face of this Earth. New revelations and new conclusions about the Egyptian Sphinx and a nearby temple are pretty amazing stuff. When I first saw this documentary back in the 90s I was riveted.
That is, until the mumbo-jumbo pseudo science about ancient humans from a lost continent and aliens reared their head. I mean, why throw that in there as a serious contemplation to what had been a solid and serious documentary? Just why?
But, never mind. John Anthony West puts his ideas forward, and Charlton Heston narrates what could have been one of the greatest historical documentaries of all time. But, even West himself says all the other kooky crap associated with his ideas is, just that, an unfortunate association, because all he's done is taken the science a few extra steps to really examine what the geological evidence states about the Egyptian Sphinx, and, form there, to draw likely conclusions about what that evidence states.
And it is compelling beyond belief. It says that civilization may be older than we thought by many orders of magnitude, and that the cradle of civilization may be near the Sphinx itself, whose life may have started out as a simple temple to some local animist deity, but, through the eons, was transformed into what we have today.
Really, if you can get by the junk science part, and just focus on West's research, you should have an enjoyable time of it.
Give it a watch and see what you think.
*EDIT* A more recent documentary aired by the Smithsonian examines the same evidence, draws some of the same hard factual inferences made in this documentary, but gives a more cogent and solid theory of conclusion, which holds up better to scrutiny, and gybes better with known facts regarding construction techniques: "Secrets - The Sphinx"
