The stones on PumaPunku are on the order of 1-200 tons.
The picture you show is from Baalbek and shows a stone weighing about 800-1000 tons.
The largest mobile/truck crane (Liebherr) can lift 1200 tons. The largest fixed/gantry crane (Taisun) can lift an eye popping 20,000 tons!!!
So we need to stop this Erik von Daniken insanity “we could not lift it with a bunch of our cranes today” It’s getting silly.
But let’s put all that aside. You see the stones there, how do YOU think they moved them?
Aliens.
duh...
Lifting and moving from a prepared site is one thing. Cutting that stone out of a mountain and moving it miles and miles to that location is another.
We could not do that today, I still maintain. (and if we could, it is only with the biggest industrial machinery we have- how did they do it 10,000 years ago?)
