We’ve been watching a show that discusses the stone work of numerous worldwide structures built way before BC. Some of the stone work is precision cut, no tool markings, with inside square cutouts that cannot are difficult to do today. Some stone work weighs hundreds of tons. What needs to be found out is how did they do it?

It's obvious that this was done by smacking one stone up against another stone. /s

Pumapunku..... Even modern day tools can’t replicate it.
