I always found it ironically low IQ when someone see a marvel of ancient architecture, has no clue how that civilization could have achieved that and project onto them "nu uh, THEY were too stupid to figure it because I can't, and I am better than them!".

And instead of discovering which engeneering tech they developped for it, or just be content appreciating what others did, go for "supernatural magic/aliens beyond our comprehension".

Specifically, the Ancient Aliens thing isn't racist. At all. It's loonies obsesses with seeing extra-terrestrials everywhere, including as the facilitating factor for major technological developments of Western/White civilizations.

But race grifters don't care, and won't change their tune after learning the Alien Loonies credit to aliens Western tech too.

Race grifters are Ancient Racist Loonies. Every single shortcoming they have will be blamed on Ancient Racists, especially when there wasen't any to blame.
