I thik that the egyptians might not have build the pyramids or might have been aided by the Babylonians or the Assyrians who had at the time a higher level of comprehension of mathematics and they were able (lets not try to put aliens in this theory) to build the pyramids with slaves and with the help of the Babylonians that could help them calculate the angle of the stones so they would all fit ...
ok now you probably think im crazy but the reason i came up with this tehry is that Babylonian god representations were found in South America which is one of the only other place in the wolrd where there are Pyramids. Also more similarities between Babylonians and South American were found like statues of Babylonians gods and the same in Egypt like representations of the pharaon with 2 left handed hands (a sing of divinity in Babylonian culture)
So i beleive that with all they have in common these cultures must of been influenced by a comon culture and the only one that makes sense here would be the babylonians.
Now your probably thinking how the hell would the Babylonians get to South America well i would say During the second ice age or perhaps by boat.
Ok plz ppl tell me what u think.... thx alot
