Is there a God? Is there no God? Is there God who doesn't care about us? These are tricky questions—in There Is No Dog, not even the people who work with God every day quite know the answers. Should we have faith in God … or should we just have faith in ourselves? Mortals and immortals alike struggle with these questions throughout the novel. In the end, the only answer we seem to get is faith that things will be better in the future.

Godhood is about creation rather than preservation. Because Bob created (almost) everything on Earth, it's really he who is God.
