It's also possible that there's a powerful witch that makes it so that people believe in basic physical laws despite them not actually holding - such that magic is possible.
The rational reaction to philosphical conundrums is to accept that indeed "you cannot know nuffin", as opposed to naively deny that the witch scenario is "impossible."
However, one most common angle to this is to postulate a form of occam's razor (which, of course one must keep in mind is a metaphysical commitment too.) With that in hand, you can reason to reject a lot of ideas - e.g. since there existing a god with a yellow hat on being just as random as there existing a god with a green hat on, we can say, based on occam's razor, that we have no epistemological access to an argument for either of those.
And from a practical perspective, adopting apriori likelyhood heuristics then also lead us to act as if it's very unlikely that everybody but yourself is a philosophical zombie.
