The universe does not exist as we perceive it, I have no doubt about that. We perceive four dimensions counting time, but there are a lot more than that.
we see only what our eyes allow us to see.

agreed on that. the bible (and i believe Jesus speaks of these things too) says each type of creature/object in the creation has its own “glory”, that they communicate (we can’t hear), that there is a powerful metaphysical realm with armies of supernatural entities who are powerful themselves (humans faint, fall down, etc whenever they encounter one) and have their own organizational structure and dominion over which they exert control (good or bad). We cant see them ordinarily.
