I've seen that stuff.
The supposed tuning rods along the causeway were steel but pyramids were made in the bronze age.
It's also kooky hippy Terrence McKenner/Alan Watts hoodoo.
It's from the recount of a caliph that was told that by a local copt who was probably talking shit.
It was in the 900s iirc, which is at least 3.5k years after it was built.
