I saw a guy successfully demonstrate how to fit large stones together. He used a technique of slamming a smaller stone against the large, thus chipping off the right amount to allow stones to fit very tightly.
It was a demonstration revealing that this is one way a person could have produced those stones in South America, that fit very tightly.
His example was impressive.
We don’t give ancient people enough credit for having found ingenious ways of doing things that our own lines of thought and investigation haven’t yet accessed.
Some past civilizations existed for thousands of years; and it seems that people could have observed a lot of things and - by virtue of their unique mindsets - figured out some very clever stuff, in all of that time.
We think that we are the first, great ‘scientific’ civilization; but other and very different approaches to ‘science’ may have gone before.
Another way to create those massive perfectly fitting stones is to come up with a superior formula for a concrete and stack bags full of the stuff. Instant perfect blocks.
Modern people living in incredible luxury, taking all for granted, grossly underestimate how brute force & prolonged experience can produce quality results.
As my father was fond of saying, “brute force and ignorance gets the job done.”
Could he slam a 80 ton stone against a 140 tonner? Dang, I’d pay to see that.
