I argue that classical theism has a significant advantage as a theory of the First Cause over Graham Oppy's naturalistic account. This is because classical theism not only gives us a clear answer to the question of how many first causes there are but also because it explains why there is that number and not another. In comparison, Oppy's ‘initial physical state’ account seemingly leaves these questions hopelessly open, and so does his ‘metaphysical simples’ proposal for a foundational layer of reality. I end by exploring two arguments from omnipotence and perfection that could be of use also to non-classical theists.
