The existence of God or otherwise here is kind of irrelevant, because even if we had proof of the existence of God it still wouldn't be clear what we should do about it  - should we sing hymns? light incense? sacrifice goats? wear funny hats?

I can prove the existence of the Sun, but it's mere existence isn't enough to make me want to worship it.

What I do argue is that whatever god may exist is utterly irrelevant to our daily lives, and does not interact with our universe, at least in ways that are measurable or meaningful. Miracles and supernatural revelation have no place in our (admittedly limited) understanding of reality.
