Answer this.....If there ever was a time when NOTHING existed....how can there be stuff today? You keep doing the Mr. Bojangles soft shoe dance around that question.
And the next step of the non-sensical stuff that I mentioned earlier: false dichotomies.
It isn't a limited decision between "a God" and "nothing".
But even if that kind of invalidates your whole question, I'll try to explain my answer to it.
As others have said... we have to find what "nothing" is first. Let's take a look at your attempt at a definition:
"Nothing is void of everything. Complete and utter emptiness. Non-existent.
That may be "common sense"... but I don't think you went far enough.
"Emptiness"... now what is that? If there was "nothing", wouldn't that mean that even "emptiness" does not exist?
See, counterintuitive as it may be, counter to "common sense" as it may be... "nothing" is very hard to describe. We don't know "nothing". We don't have any experience with "nothing". Because in our space-time-matter universe, there never is "nothing".
So to use our space-time-matter "common sense" on something that has nothing to do with it at all... this is not a valid use of logic. (For that matter, if there is "nothing", would there be "logic"?)
Thus it is not possible for us to say what "nothing" would be like, and what could come from it.
Personally, I don't see "nothing" as "complete and utter emptiness". I see it as "something that you could never ever explain or describe. Something that is completely different from everything we know."
And thus the answer to your question would be:
"If there ever was a time when NOTHING existed....how can there be stuff today?"
"Well, there is nothing to do it. But there is also nothing to not do it."
