The onus is not on me to disprove God, it’s on believers to prove what they believe is true.

??? There’s no onus on me, because there’s no penalty on me for NOT proving it. However, theoretically, there could be a penalty on you for not believing it. Which is the more logical course of action?

what sort of shatter-proof argument would be acceptable?

I don’t believe there is one, at this point in human history. Even evolution is a theory. I doubt anyone could prove conclusively that there is a deity who created the universe, any more than one could prove conclusively that there is NOT a deity who created the universe.

Which is all actually a different discussion than what I believe the OP intended. If I may be so bold as to reword it, I think he’s asking “If there is no deity who created the universe, then where did the universe come from?”
