I am surprised by your lack of knowledge. The original historical data we have of our origins comes from the Sumerian civilization. Later inherited by the Babylonians, Assyrians, Akkadians and so on. On the other hand, interestingly enough, the pseudo scientific fictional theory of human evolution does come from a clan or a group of followers with a specific agenda.
Yes I was referring to the original writings coming from ancient times. No I'm not trying to bait you, my comment about the "scientific" community was generalized. My whole reply did contain a degree of jerk due to yours in your previous reply. No feelings though.
