Does anybody know if there has been any non-fiction books.......?

Check out the site below...it has many non-fiction books concerning the Anasazi.....

there is also the Hopewell peoples....

Maybe you could clarify for me what you're looking for? I've read a few creation myths of different native cultures based on the creator spirit making human beings once, and not liking how they turned out, destroyed everything and started again. I've also heard of the term 'those who came before' referring to their anscestors, rather than a completely unrelated and seperate people. I've also heard of Atlantian type claims of para-psychologists and such saying that the ruins of Atlantis exist in the Grand Canyon. I'm not an expert on ancient American history, but I've got a library background. Here's something I found today for you.

Dirt Brother's Archaelogical Book Reviews

Most of it is on Native American cultures, but perhaps you will get lucky. The site is scientifically based, rather than para-scientifically or mythically based though.

I did find this little gem too:

Does this help at all? If not, what else can you share to narrow the search?

ADDITIONAL SEARCH:

After reading your additions, I searched for earliest human habitation evedence in the Americas. As of 1997, evedence was confirmed that a pre-clovis culture existed in the Americas, predating the clovis sites by a 1000 years.

Here's a site for you:

http://www.archaeology.org/online/features/clovis/

This site may help give you a starting point for doing more indepth and focused research on your own. It's not a book, but I hope it helps.

I don't know because anthropology is not my field. Try a search using a university and research oriented tool "for the people who came before" and see if it returns anything. If that fails, contact a good museum of anthropology in North America to see if they can help you. If there is any evidence for these people, someone must have done some research on it.

Oh my, so many ways of finding the infomation there is, and I have included the links you will need to help you. Of course, in addition to this, you can also use the resources at your local library, they are only too happy to help you with your searches and queries.
