I have gone up in the Pyramids and the stones are so close together you can't force a playing card between them and (they are) in perfect alignment. So those people must have had some hydraulics or something. You take 20 men, put them around a big stone, their legs would get in the way. Even if they could lift it, 20 pairs of legs hitting against each other would throw it off balance. And they would not have it in exact alignment. Not even a fraction of an inch off.
