In the Bible the genesis of homicide is told like this: Cain, the tiller of the ground, met his sheep-tending brother, Abel, in a field. Was there a dispute over land? Cain killed his brother and then lied to God (and himself) about what he had done. After the murder Cain ventured east of Eden to build the first city. There you have it—human civilization founded in murder. And the rest is history. Literally.
