Isn't deciding the rules of the game as a human pretty arrogant?
If the game you speak of is how to define or deal with the concept of God, then I don't see any alternative to speak of, therefore there is no way of establishing whether it is at all arrogant.
Maybe you meant something else?
To even continue the discussion though is a bit of a nuisance, because things have to be defined. Like "universe", "physical", "experience", and even "effects". Not to mention, it's pretty weird for me to make a distinction between the universe and God at the best of times. That distinction simply isn't there.
Your privilege, certainly.
All the same, others will see such a distinction, or handle the concept in ways that clash with yours.
You can either not mind that or attempt to reach understandings.
