Depends on what you believe in. At this day and age religion still has influence.
The Universe is part of what GOD is.
Well, it's not just ONE verse - which the prefix "uni" refers to.
I have no idea, what or who caused the Multiverse to pop up. May have been the Christian God, some other god or perhaps we're just living in a bubble of some tiny hyper-non-dimensional goblin's pee pond. Who the hell knows...
I'm agnostic and although I have some answers, there will always be more questions - that is the nature of our being.
I suppose that depends on your definition of God...
Be more specific what god? Zeus?
Given this definition of irrational (https://www.merriam-webster.com...ary/irrational):
: not rational: such as a (1) : not endowed with reason or understanding
I would say yes. It's a belief independent of evidence.
Okay. Let me try this again..
A belief is a conviction based on personal faith. They cannot be disproved or even contested in a rational or logical manner.
Your remark that it doesn't matter if you believe it or don't. God said it, that settles it. is an example of a belief.
It's no less rational than attributing misfortune to black cats.
