Mojaco  

I invision life to be some sort of computer game from heaven. A game you play to enhance yourself, to add to your personality

You log in as whatever you want, be it a human or an ape, explaining why humans get more and more and animals less and less

Then you lead a life unaware of the game. You experience love and happyness as if for the first time, or sadness and sorrow

Once you die, you'll be back in heaven, aware of the game. The life your lived has forever become a part of your heaven self

This might not go and sell as well as the Bible though
