Don’t remember the name of the show on Discovery or Ancient Aliens or whateve, but the subject was the Sphinx and its relation to a star or constellation.
An archeologist/astronomer was making the argument that the physical characteristics of the Sphinx, specifically the evidence of water erosion had to date the massive statue to at least 10,000 years earlier than any of the later Egyptian pharoahs.
He made the argument that the statue’s alignment was toward some star or constellation that was in the Eastern sky at that earlier time. Lion constellation?
As you can see, I don’t remember all the facts exactly, but it was a very interesting program—and the argument about evidence of water erosion seemed persuasive.
There is good evidence that the Sphinx temple, the Sphinx and the Causeway were built upon by the Pyramids.
