We probably shouldn't mention this in...certain groups. Where certain people still quote Edgar Cayce on the subject:
Atlantis was something that Plato completely pulled out of his ass just so Socrates could have something to talk about, and he specifically mentions in his writing that Atlantis is a completely hypothetical city.:rofl:
In Egypt I heard some great rants (from Egyptians) about the Charlton Heston/Space Alien Theories of Pyramid Building. Many tour guides in Egypt are moonlighting grad students or even teachers. Boy, do they HATE that crap!
Funny thing is, you can stand at the Step Pyramid in Saqqara and see the whole history of Egyptian pyramid building right before your eyes. If it's a rare clear day in the Cairo area, you're looking at the Step Pyramid (the first one built by Pharoah Djoser); in the middle distance you can see the Bent and Red pyramids (built later by Pharoah Sneferu); and WAY off, barely visible, the Giza Plateau with the Great Pyramid of Cheops and those of his offspring.
The woos who push the alien theory seem to ignore everything except the Giza pyramids, which always struck me as weird.
Right here on DU, we once had a fellow who claimed he, his girlfriend, and other Enlightened People had "out-of-body meetups" inside the Great Pyramid.
Didn't get a chance to ask him my verifying question - what grand structure is located right across the street from the Giza Pyramids?
