I’m late to the thread and missed the fascinating discussion. Thanks for all the interesting information.
Something you both might find interesting are the books “Forbidden Archaeology”, and its condensed version “The Hidden History of the Human Race”, by Michael Cremo and Richard Thompson - https://www.amazon.com/Forbidden-Archaeology-Michael-Cremo-ebook/dp/B004LE7OHI/ref=sr_1_1?s=books&ie=UTF8&qid=1488156347&sr=1-1&keywords=forbidden+archeology
I recently ran across a fascinating book that I did buy, and am currently reading. Its called 'Dead Men's Secrets', by Jonathan Gray. In the book, he lists hundreds of examples of suppressed and little known evidence of ancient advanced cultures. Search his name on YouTube, and you can find lots of his interviews, too.
Here's a link to his book:
DEAD MEN'S SECRETS: Tantalising Hints of a Lost Super Race
