In before the firestorm!
There are two historic figures who discuss how human life was created and from that discussion, draw conclusions on how we are to live.
One, claims that we are created in the image of God, but flawed by our own selfish desires, and therefore must seek repentence and act against those desires. His advice tells us that it is better to love our neighbor than ourselves.
The other, claims that we are descended from apes. Since there is no creator, there is no basis for morality beyond a human construct. The concept of "survival of the fittest" tells us that survival is our primary driving force and that leads to the exact opposite conclusion "it is better to love ourselves than our neighbors".
One approach, if followed leads to a human race that evolves into a world of peace. The other leads to a human race that evolves into destruction.
Ironic, eh?
