I often wonder from where the source for these dates and explanations come. The only thing that is new is that the western culture is now noticing what has been a way of life for tens of thousands of years for the indigenous people. And, western culture is having a very difficult time with it as it defies all they have been taught and believe. I can tell you that the children resist this "savior" responsibility. It makes them very uncomfortable.
The good thing is that western culture is finally beginning to return to the truth.
