But according to Graham, a cataclysmic event caused the sudden extinction of this civilization. Which means that it happened so suddenly and bruskly that these people could not have had time to spread out geographically. And that means that if we excavate the surrounding areas of these monuments where there would have been a concentration of these populations, we would have found human remains.
The only thing that comes close to this hypothesis are the tombs near the Great Pyramids, which are claimed to be the pyramids' builders.
