You can trace all biblical stories back to three main areas...
China/Asia... The yellow emporer and the Golden Aeon/Age/Era...
North Africa...
Native Americans... (though that isn't the true name for them... They live by different names throughout their land...)
They each a slightly different version of their own 'truth' or knowledge, they teach their families in much the same and for the most part the ideals they would have tought were of harmony with those around them... With the environment and in their own lives... Spirituality was their life, it wqasn't till the written word came along and then with 'law' that there was Dogma and holier than thou...
The Bible we know today, including the Kuran/Quran is from the Egyptian / Etheopian tales or religion...
