We're talking about 140 tonne rocks being put together to form those structures and assembled without mortar in such a way that one can't slip a piece of paper in between rocks.

As the other comment here says, this isn't a mystery. It's just extremely labour-intensive.

And as I said there, I don't find that kind of blaise response as convincing or substantial. Labour intensive way of lifting and lapping 140 tonne rocks?
