Based on the logic of Mr. Unknown, that everything must have a creator. I don't mean to be cliche, but then what created the creator? And if you say the creator has always been, why can't the same be inferred about the universe. And even then, all that suggests is that there is a powerful force. We still don't know what it is or who it is, and we damn sure don't know if he's ever directly influenced the people in our world. So even by your thinking, "God" is still not certain, only a higher power. Inferring the existence of something doesn't allow you to then create stories where it is the main character.
