It goes both ways in my view. I'd like to see how - and why - they built certain things like the Pyramids or those megalithic stone artifacts we have no explanation for nor any hope of duplicating with what we think their technological levels were. Even our own methods seem strained to duplicate them.

That's one of my favorite YT video categories, even though I don't go along with most of the theories the users posit.
