(not trying to bash you via multiple threads) as a grad of both catholic school (HS) and biology (college) i kinda love getting into this shit.
Anyway,
there's some things science likely may not ever be able to explain (especially in our time), particularly pre-big bang. There's plenty of theories based on the available evidence attempting to describe where matter came from pre big bang, and of course theologians often speculate "maybe this is where we come into the picture". To many, especially modern theologians, this situation acts as a sort of Schrodinger's cat paradox (in which we assume both conclusions ARE right) when thinking of what or "who" was involved in the pre big bang. However, I am compelled to side with theoretical physics which is persistently chipping away at understanding this cosmic event over those that claim a nonphysical being created all that which is physical. My point is that there may be things we never can know, yet it makes more logical sense to infer possibilities that are grounded in previously observed phenomena, via astrophysics, over an yet to be seen or, by many modern theological accounts, an unseeable alternative, a superior non-physical "god" being.
A mental game i like is... you are in a room with a friend, and he asks you to guess what is behind the brick wall in the next room over; what is your best guess? Logic would suggest it is something that you have seen before: possibly a dog or a pizza. Contrarily, even if you could never know, it is unlikely you would guess that it is something outlandish or that you have never seen before: like an alien, a blue whale, or something NONPHYSICAL.
