Oh, yeah. There is none so blind as he who will not see. LOL
Part of the problem, besides being closeminded, is disassociation. How can you identify something if you have no idea what it is? Modern people, most that is, have no idea about ancient tools, etc.
Grew up close to Serpent Mound. Fascinating place, and it took a lot of effort for the peoples that built it. They didn’t move that much earth on a whim, esp when they had more important things to do—like finding food.
Something else I’ve always wondered about—completely unrelated. If Kentucky was known to the indians that lived there as the dark and bloody ground, how big was the battle that gave it that name? Where did all the bodies go? Assuming wild animals accounted for a great many, shouldn’t there have been a great many bones left lying around? How many generations had to pass before the specifics were lost and nothing but the memory of fear was left? Who was fighting whom, etc. INquiring minds want to know!! LOL
