God's God

[Mystic]

I don't agree with the reasoning. First it can be (for all we know), the universe needed a cause outside the universe. We don't know it doesn't or that we won't ever know it does. Furthermore, it can be that existence constantly needs a cause. Empirically, we can't know that, but what if we know it ontologically? It's circular to argue we can't know this ontologically from the empirical perspective. If that's true, God can be his own cause of his own existence, by his very nature of being supernatural and an immensely powerful while lesser type existence, like us, like atoms, like quarks, may need a constant maintainer to their existence.

Furthermore, is the necessary being vs possible beings discussion. That which is possible needs an explanation viewpoint, but that which possibly necessary doesn't need, by virtue that it being necessary is an explanation.

Yes there is silly arguments on both sides. This is one of them.
