Answer 9

Theories about extraterrestrials generally stem from the incredulity of some people that indigenous people, or people not from their own ancestry, could have acomplished some of the things they did.

"Those brown-skinned Egyptians could not possibly have constructed those giant pyramids, certainly not before Europe had cities! Aliens did it!" Well, that's the general idea. It's not even always aliens that fill the role. It was assumed that the Native Americans could not have built the giant mounds that existed all over what is now the U.S., so it was imagined that a race of "mound builders" (fair featured, most likely) did it, and that those people were wiped out by the "savages" that lived there when Europeans showed up.

Generally, argument number 1 in support of ET involvement is that things were built or accomplished that humans could not possibly have done. If you take a moment to think about that, it is, at the very least, a conclusion that actually lacks imagination, if not research.
