>>3681448>You still haven't gotten to the megalith structures that even our most powerful crane can't lift a single element of them off the ground.You really underestimate what cranes can lift.
To make a stonehenge today it would take 5 men with angle grinders 1 truck and 1 crane a month of work.
Ancient guys could have been working on it for generations.
There also are some things that are just carved into the mountain, like giant buddha. Well thats simply a lot of hitting a mountain with a stone.
