hey you know that guy Zecharia sitchin made his first book called "the 12th planet"
in it he traces the existing of humans all the way to the sumarians and ends with our being how it is today...
its pretty nice,, makes perfect sense
he is an archeologist and translated the ancient sumarian language....
I really reccoment all of you to listen to this book
