The evil-god challenge is a challenge for theists to show that belief in God is more reasonable than belief in evil-god. In this article, I show that whether or not evil-god exists, belief in evil-god is unjustified. But this isn’t the case for belief in God: belief in God is probably justified if theism is true. And hence belief in God is (significantly) more reasonable than belief in evil-god, and the evil-god challenge has been answered.
