Where is the record of all these tens of thousands of years of indigenous history? It doesn't exist because nobody had any way to record it. The indigenous peoples weren't advanced enough to have writing. The blissful image of learned natives communing with nature in peace and harmony is an invention. Natives were as warlike as any other people of that era, and constantly killing each other off. Their average lifespans were about thirty years, and they worshiped all kinds of primitive gods because they had no science and thought the gods controlled everything.
