My point was that knowledge is just as "meaningless" if you accept the existence of any other realm. If the natural realm is all there is, knowledge is nothing more than a human concept; neurons firing in our brains.
If the supernatural realm exists as well, then knowledge is nothing more than <insert supernatural explanation for knowledge here>. Any way you look at it, it boils down to one realm asserting knowledge as something, and the improvability of that assertion.
