I will prove to you that God exists

That wasn’t the question, though, was it? I think Sheldon was asking what, if anything, is your standard for disbelieve generally. If you don’t have such a standard, that’s fine, but it makes any argument regarding your beliefs inherently weak.

What's yours?

About the highest level of certainty we can have is a scientifically established claims that pass the rigors of critique and repeatable experiments that confirm the hypothesis. Unfortunately not all theories can be so tested. 

The second level is evidence beyond a reasonable doubt. It doesn't mean all doubt is erased but reasonable doubt is.

The third level is a simple preponderance of evidence. In the mind of the beholder there is more evidence in favor of one claim than against it. Or there is more evidence that disfavors the claim than for it.

Evidence are facts that make a claim more or less probable.

If those are your standards, then your belief in a deliberately created universe doesn’t meet them.
