What exists does so in space and time. 'Things' exist. God does not. He's not a thing, though most conceive him as such. They are 'things.' God must be too. Anthropomorphism. God does not exist, he creates.* His Reality is only available through faith. No faith. No God. For the denier of faith only the body exists, that which is our material self. This also helps explain the fall from grace.
*Soren Kierkegaard
