One response to the idea which I'd like to see addressed is: what if you're the background character in someone else's drama, whom "God" has made purely to meet some gruesome fate in order to test their faith?
At the age of five, Skagra decided emphatically that God did not exist. This revelation tends to make most people in the universe who have it react in one of two ways - with relief or with despair. Only Skagra responded to it by thinking, 'Wait a second. That means there's a situation vacant.'
