Steve, I don't know. That shaman was part of the Natufian paleloithic culture in Israel. It would be interesting to know how it evolved into the religious culture we know from the bible.
The dates they give would suggest a higher period of time from Sri Yuketeswars' model. This does not bear out in the explanations of their behaviors. i can't make sense of it. This would have been at the height of the Golden Era. The spiritual evolution should have been much higher then our own. i am unable to put some scientific data explanations together with Sri Yukteswars views of the yugas. There r other higher cultures whose behaviors have been explained much differently then the status quo of conventional scientists. It leaves a lot of questions.
Cayce's approximate date of 9,900 years B.C. for the final destruction of Atlantis! (Refer to readings 364-4 and 288-1).
