Can't we make a distinction here between science and philosophy?
I can't, no. Because I find my physics impinges on what I once thought was pure philosophy and/or theology.
If we take the idea of God that you have been using: creator, ultimate being, etc, then it would hardly be sensible to consider that entity as constrained by internal properties of the creation. At least, that is an assumption I am making.
When General Relativity tells me that time is merely an internal property of the universe, it leaves me with little choice than to consider this God as outside/unbound by what we call time.
Physics places lower limits on this creator God's attributes.
