A friend of mine took part in an experiment to drag Stonehenge-size stones and it was trivial. You just have lots of people and rollers. You raise them by working on balance points - sort of like a seesaw.
these places where they built with massive monolith stones the quarries for them always seem to have been around 20ft higher some many miles away.
it seems they purposely pick a spot somewhere downhill of a quarry to build, I guess it's mostly gentle slopes for miles they are moving along.
with hundreds/thousands of men it's probably quite possible.
the mystery is who actually cut them and who moved them to baalbek, the theory is the romans didn't know about the ones still in the quarry or they would have been cut in to smaller blocks by the romans instead of being left untouched all the way to modern day.
if you look at photos of baalbek the foundation stones are crazy huge, the building stones on top look tiny in comparison almost the romans came along and built on top of some ruins
people always claim we couldn't move a 1500 ton stone block with modern machines so it's impossible to have been done thousands of years ago.
but as I shown with videos we can lift 20,000 tons, we even have a plane that can transport 250 tons (how amazing is that? getting 250tons of cargo to fly)
Nasa regularly rolled around 7000 tons at 1mph to the launch site.
theres been tests where one man has shown how you can move a muti ton pillow with 1 person who can hen even get the pillow to stand up right, (videos on youtube)
when you have hundreds of thousands of people surely 1500tons is deadly to move and needs a lot of effort but its not impossible.
we don't need aliens or giants we just need to know if it was actually the romans or someone else doing it
