And you know this how? They didn't leave any written records because they hadn't invented writing yet. They didn't leave any films or sound recordings because they hadn't invented those technologies either. This is just romanticized speculation about people who aren't here to speak for themselves. Again, please tell us where you learned this remarkable information. I hope you're not basing this on the accounts of explorers in the Colonial Era. They generally fell into two camps: either portraying the Noble Savage as better than their own people, or regarding them as animals who could be enslaved and sold. The few Paleolithic (pre-agricultural) tribes left on earth today have by now had far too much contact with civilization to be accepted as accurate examples of the culture of the prehistoric past. They're "stone age people with chainsaws and iPods."
