Presumably this refers to the passage in Histories 2.124 where Herodotus writes of “chambers on the hill upon which the pyramids stand, which he caused to be made as sepulchral chambers for himself in an island, having conducted thither a channel from the Nile.” Note that Herodotus attributes this simply to the Giza plateau, not the pyramid itself. It’s possible that this refers to the Osiris Shaft, interpreted as a cenotaph for Osiris, and located belowground at Giza. I have no idea what the word “Ezerius” is supposed to refer to but sounds enough like Osiris that perhaps the author of our account misunderstood von Däniken’s heavily accented words.
According to the account of von Däniken’s speech in Ghost Diaries, Egyptologists have used radar to discover hidden rooms in the Great Pyramid filled with “red writing” different from the quarry marks found above the King’s Chamber. How radar would reveal “writing”—and its color!—is beyond me. They also allegedly discovered an “actual lake” below the pyramid, which he alleged might be the burial site of an ancient astronaut.
Among other breakthroughs at Contact in the Desert was the revelation by Marshall Klarfeld that the Anunnaki are also the giant Nephilim of the Bible since they are nine feet tall. Daniel Sheehan also claimed that the Catholic Church would announce the existence of aliens shortly. But are they really aliens if they are also Nephilim?
Paul Andrews, the cofounder of Contact in the Desert, told USA Today that at the conference researchers are not allowed to contradict or disagree with one another, and no “snickering” is allowed, no matter how ridiculous the theory—or, presumably, how wrong the evidence. Thus, USA Today talked to ancient astronaut theorists, believers in Atlantis, proponents of a flat earth, and other advocates of ideas that, logically, are difficult to reconcile. The only thing everyone agreed upon was that the United States government was all-powerful and able to bend history to its will, except, of course, for the History Channel and Contact in the Desert, where brave patriots take arms against a sea of lies and somehow have discovered the truth despite the best efforts of the government and interdimensional alien-Nephilim-Bigfoots.
