I don't think you're grasping how heavy 1200 tons is Mush.........."lift one end" with what?.......what could be strong enough to use as a lever? There's a lot of difference between the lintols at Stone Henge that were lifted like that, and the stones at Baalbeck.......And even if you could get a lever strong enough, how do you get enough manpower on it? I think primitive men did it, but no idea how they did it?
Truther the pyramids, an baelbeck stones were all built an moved by giants, plain an simple, plenty of evidence, to back it up,
