Sweet, I love theorizing about that far in the past.  Since it's so uncertain and subjective to accurately predict history of a civilization that far back, I find that you can get many awe inspiring theories.  One, I am completely captivated by is that the visitors from other planets arrived to edify our primitive ancestors  with mathematics and knowledge of astronomy.
