What I would ask you is where do we come from.

It is important to maintain a constant awareness of and vigilant respect of our epistemological limits. There is no reason to jump to any conclusions without hard evidence or logical necessity.

Was it evolution via the big bang and/or creation through some kind of creator and/or other things?

Look, even if everything was created by some "intelligent designer", that supposition alone provides zero support for any version of "YHWH".

It also provides zero support for any specific human moral framework.

DEISM (intelligent design) = ATHEISM

The two are functionally indistinguishable.
