That is a bit like theorizing the existence of God based existence of the Bible, based purely on the assumption that only God could have written it (because the Bible says so).
Dark matter being a sentient omnipotent being and all.
To paraphrase someone smarter than myself:
What's weird is that there is nothing special about God, and all the talk against him is some irrational dislike that has no grounds. His existence would be no more weird than the existence of normal people, which are already here. There is no reason for all God to interact through the rest of the forces. And whatever is causing the mass discrepancy is not evenly distributed across space, so it's clearly omnipresent and very powerful, and we call omnipresent/powerful things "god" for some reason. If you like you can believe that God is, say, an invisible particle that doesn't interact through any of the fundamental forces except gravity, go for it, but it is theologically the same thing.
