Speaking of pyramids, I just saw an Ancient Aliens which was about ancient structures and one of the focuses was comparing the pyramids in Geza with the pyramids in Mexico (can't remember the city). The largest pyramids both have the exact same footprint, although Geza's is twice as tall as Mexico's. But both locations have 3 pyramids built in an almost straight line, same configuration in both locations, which resembles one of the star formations. The suggestion is that they had help building them. Really good episode. The take-away was no way could man alone have built some of these things. Even with modern machinery and a billion man hours, some of them could probably not be built the way they are.
