Mounds were built over or attributed to other people and turned into protected lands. We're told "indigenous" people who haven't progressed beyond a hut were once Earth terra-formers. And they stacked all those rocks up, too.

What I especially like about the American giants were that 1, they were supposedly red-headed and 2, they were found up and down the east coast, Midwest and all the way out to California. They were prolific.
