Explanation: A lunatic proposal that sometimes is passed around is that many of the great architectural marvels of antiquity were constructed or assisted by ANCIENT ALIENS despite the utter lack of evidence to even vaguely suggest such a thing, and often with very basic mistakes about the history or construction of the questioned structures. Curiously, such accusations of assistance by ancient aliens are almost exclusively leveled towards non-white civilizations by extremely Eurocentric authors.
This is only a coincidence, I'm sure. /s
