And why did they build such crappy masonry? If they could slice rocks like a knife through clay, why do their walls look like this:
You have big rocks, little rocks, crooked rocks, thin rocks, rocks with corners missing, horizontal joints that aren't even close to level, vertical joints that are crooked, and rocks that are obviously filler. It looks more like a bunch of humans simply carved whatever rocks they could find to fit each other as best as they could.
It's too bad they didn't hang around so we could teach them about our space age reinforced concrete.
It doesn't take a genius to realise that whoever built that was different to the builders of Sacsayhuaman and the precision polygonal walls in Cuzco.
Nothing more to say apart from the Inca built the cruder rubble and adobe walls.
Who was responsible for the precision work we do not know.
