You can always turn a claim into a logically equivalent claim of the non-existence of any counterexamples.

    “For every instance, e equals mc²”

is logically equivalent to

    “There is no instance where e does not equal mc².”

That combined with your belief that claims of non-existence can't be held with any degree of certainty means you believe that no claim can ever be held with any degree of certainty. Which is not a very interesting insight.

This is an equally unsupportable claim, though. This requires enumeration of the entire state of the universe, an impossibility. This is just the standard swan problem (https://en.wikipedia.org/wiki/Black_swan_theory). What you have is a model you're very confident in without the deductively-rational basis your diction implies.
