Instead of thinking of it as a bang in an existing space-time, the way to conceptualize it is the collapsing of a universal wave function from a superposition of all possible universal states. Of which our universe is just one potential possibility. Space time is a function of the collapsing state.
I think I understand that to a certain extent. But where does the universal wave function exist to begin with? There must be some construct it exists within.
Why? I would look at Occam’s razor, believing there must be an outer layer (or a creator of god) just leads to an infinite regress. It’s much more likely that the thing is just eternal according to that logic
