Gotta love how humans always look back on old historical monuments/structures from before we had machines and are arrogant enough to assume ancient people were too dumb to figure out things like moving rocks that were too heavy to carry by hand.

They cut cylinders, rolled them downhill with rope and levers, stood them up using another one as a fulcrum for the lever, and carved them in place. This was genius then. Today it’s high school physics. It should be obvious to us how they did it.
