You can assume all kinds of scenarios....but the genetic DNA link shows divine intervention not of this world.

Religious people claim it all came out of the middle east created by one God....of course it's their God.

Common sense tells me because of the different races of people and various ancient religions on this planet that Earth was seeded by several different Gods...aka Aliens to our planet.
