Utter nonsense.
I lost 3 IQ points just watching the show.
The pyramids were never used as a "tomb of the pharos". No bodies have ever been found in any Egyption pyramid. Thats what the valley of the kings is for.
Way back in the early 19th century some western professor said "they must be the tombs of the pharos" and everyone has been parroting this nonsense ever since.
The primary mystery should be who actually built them, hint not the egyptians, how was the project management accomplished.
The pyramids were built from the inside out requiring 60 ton rocke to be precisely cut and moved hundreds of miles in the order necessary to construct the critical inside features. The project management and logistics would be overwhelming to people with no real written language.
The pyramid (the Gaza complex), not the crumbling ones, were discovered by wanderers in the desert who saw pointy things sticking out of the sand, near a gently flowing river and decided this would be a dandy place to settle. Then they used the casing stones as a quarry. Hardly sacred.
There are NO documents or hieroglyphic showing the construction of the pyramid, anywhere.
This from a civilization that documented EVERYTHING from harvests to bowel movements.
We have the timeline backwards. The giza complex was built first by people that really understood how to build them, the other crumbling examples were built much later by people who tried to duplicate the feats of the real builders.
