Oxygen-
I have heard about, and saw some kind of documentary on about the maps of Antartica that have been found. They are very old, and the shape of Antartica is the shape of the land that is currently buried under mega tons of ice. There is no way those maps could have been made without some kind of aerial (sp??) survailance, and back in those days, that kind of thechnology simply didn't exist. Plus, to see the land under the ice would require pretty good technology as well. One theory is that the entire crust of the earth could swing about, what used to be equator would now be near the poles, and vice-versa.
My thought is that perhaps Antartica is Atlantis - I think maybe humans (or maybe aliens??) lived on Antartica when it was in a more temperate area, and built pretty good technologies. Then the Earth's crust moved (perhaps due to the magnetic poles switching?), and the survivors barely made it to the European area (Tigres/Euphrates river valley is supposedly the starting point for modern man, I think, righ?). Most everything would be lost, except legends about flying machines, and some old maps. The missing Link, as it's called, might be found under the Antartica ice.
Just a theory, what do you guys think?
