How far reaching are God's powers?

[Mister Agenda]

What is God god of? My guess is that most believers believe that God's powers go over our solar system. So is the God a God of the whole galaxy or just part of the galaxy? Does it go beyond galaxy and God is God of the whole galactic cluster? Or the believers believe that God is in charge of all the galaxies? I mean that is a lot of galaxies, stars, planets, and whatnot.

And if God is God of the whole universe is it just this universe or is he God of all other universes, or each universe has its own God?

Psalm 82 mentions how God has meetings with other gods so we see some division of power, perhaps gods of other galaxies or universes?

Except verse 6-7 says these supposed "gods" will die like mere mortals, so not "gods" of any consequence.
Julius Caesar could be likened as one of these gods perhaps based on what people around him thought of him.  But as far as I can tell he is just food for worms now.

I remember that Psalm, there's a big meeting where God demotes the other gods for not being good at their jobs.

God's power is far greater than most realize. Perhaps the most terrifying indication of His power is the fact that He had no beginning, a concept we can hardly even begin to imagine.

Some cosmological theories posit that the universe had no ultimate beginning, it's always been around in some form. The math works and it doesn't violate what we know of physics. What we can get our minds around doesn't seem to have much bearing on what actually is.
