Those are the ones you should try to rebute by explaining why they are impossible. Those can prove that formation of DNA is not impossible through natural means even though we may never know which explanation is correct. Since the debate is about the plausability of abiogenesis anyway, it's not a problem.
We could argue that 100% of our experience tells us that the supernatural explains nothing so if we go down that route, the debate will go sterile fast.
By your logic, I would have been right to argue 200 years ago that man can never go to the moon because 100% of our experience men can't go the moon. That's why I said it's useless to argue through this route: it shows nothing.
The default position if you don't know should be "I don't know but I'll keep looking for a solution". That's the scientific method and it excludes supernatural because supernatural explains nothing.
If you want to know why, just look how Islam went from one of the most advanced civilization of their time to 3rd world country.

Your method of looking for things has been shown to be unreliable historically that's why scientific method excludes it.
