> But why do there have to be six kinds of knowing?

Because Buddhists love lists! Why is the path "eightfold"? Why are there four "noble truths"? Why are there 6 paramitas?

These lists are study aids - they help you to memorise the teaching, and repeat it accurately. They are not meant to be taken as metaphysical statements about reality.

> we also know what is real

Oh, do we? I think you might have trouble finding many physicists that agree with you. Truth and reality are slippery concepts. Someone who is not given to thinking about these things might take the view that it's pretty obvious what is real and what is true.

I think that outlook is rather arrogant.
