That’s basically what I’ve been saying all along. The premises of science assume that reality includes only what is consistent with the rational understanding of empirically observed material phenomena: any other alleged or hypothesized sort of reality is effectively nonexistent as far as science is concerned.

The thing that is inconvenient for you here is that you find your approach to epistemology defending the non-falsifiability of abjectly ridiculous claims such as a young earth creationism or playmates in the sky.

That’s not “inconvenient” for me at all. Unlike you, I’m not confused about the distinction between non-falsifiability and plausibility. So it doesn’t bother me in the least that many (arguably, most or all) supernatural claims are both technically unfalsifiable and completely absurd from a rational perspective.

But science falsifies all supernatural.

Nope, you’re still confused about that. Science falsifies all known rationally consistent and empirically testable claims for supernatural phenomena (so far). But that is not the same thing as falsifying the supernatural itself, which science by its very nature cannot do.
Lemme give you a frinstance. If somebody says “There’s a supernatural being who tells me how to correctly identify, without fail, unseen cards picked at random out of a deck”, science can test the related claim “I have the supernatural ability to infallibly guess unseen cards picked at random out of a deck”.
That claim is rationally consistent (i.e., it relates to objects and events, like picking and guessing cards, that fit in with our basic understanding of materiality and causality in the real world), and empirically testable (i.e., scientists can set up an experiment that can accurately assess how well the claimant actually succeeds at guessing cards).
So scientists set up a cheat-proof experiment to test this claim, and surprise surprise, I bet you anything you like it’s going to turn out that the claimant does not do any better than random chance at guessing cards. So the claim that they have an infallible ability to guess cards has been falsified, and any attempts to use that alleged ability as evidence for the existence of an alleged supernatural being now stand exposed as utter bullshit.
But that does not mean that the underlying supernatural claim “There is a supernatural being” has been falsified. It hasn’t, and it can’t be.
Testable claims can be falsified; untestable ones can’t. That’s just the price we pay for having an epistemic system as precise and powerful as science: it comes with very clear boundaries between what it can and can’t do.
Yup, I never said it wasn’t. You can insist that there is no possible reality that is undetectable by or inconsistent with science and that all supernatural claims are necessarily, absolutely bullshit, and nobody can prove you wrong. The assumption that supernatural phenomena do exist or may exist is not in any way more valid a priori than the assumption that supernatural phenomena do not or cannot exist.
All I’m doing is to point out that what you’re insisting upon so vehemently is an assumption, not a fact.
