I think you're forgetting that the supernatural is but another theory, put forth by humans, to explain our existence. It doesn't earn bonus points for being unobservable. I've seen 0 evidence supporting it, contrary to how many questions particle physics has solved.

I've simply stated that we can't draw statistics about things for which we have no evidence - which you now seem to be agreeing with.

I've posited quite the opposite of this. If there are two opposing theories, with one substantiated and one not, then the substantiated one is more likely. For example: you wouldn't say that a chicken's offspring being implanted in an egg by cosmic rays is just as likely as the egg being fertilized before it was laid because the latter is substantiated while the former has yet to have any observable truth.

I'd say 99% is a completely fair probability as the ratio of something to nothing approaches infinity.

we don't yet have evidence pertaining to any hypothesis for how it was created

I just gave you some? I don't know about you, but humans being able to replicate the exact particle that originated matter is a profound bit of evidence towards the universe not being a product of some higher power to me.
