Where did your god object come from, before creating the universe?
The things in the universe, to be more specific.
And there is no "before". Time is just a measurement.
I think it makes sense that if there's a higher being who has control over things, He's on another level of existence and surpasses our petty measurement of time.
Yes it is. Please read this.

"Metric expansion is a key feature of Big Bang cosmology"
If metric expansion is based on something that hasn't been scientifically proven, how can we use that as a basis for reality?
And you are saying the big bang cannot have happened because current science cannot explain it yet.
I'm saying that it can't be proven because we have no way to prove it yet. Until we have a way to prove it happened, it's nothing more than a hypothesis.
