"First of all, who says we can't understand the supernatural? I don't believe that for one minute, and I don't really think that there's any reason to hold that"

We cannot 'understand' supernatural simply because it would then be natural. It doesn't matter if you believe it or not. This is a truth that has been proven. Even outside the context of god, this has been examined to be the case.

"Just because something is different from us doesn't mean we can't understand it."

This phrase assumes that the 'supernatural' can even be perceived as 'different' than us, when, in reality, applying such an adjective is not applicable.

"If supernatural is something we cannot comprehend or have any thoughts about, where does the idea come from?"

I don't know where the idea came from initially. I do know however that humans tend to believe a lot of things that are false or don't exist. For example, there's no such thing as 'good' or 'evil'. There's no such thing as 'right' or 'wrong' (value terms, not truths). Society has built itself around these words, and, the words begin to take on other meanings. While there is no absolute 'right' or 'wrong' it can be said that such things are relative to the society. The term supernatural is no different than this. While the root meaning of the word is unintelligable, society has put certain constraints and values on the term in an effort to cope and make sense of it. It's quite a brain teaser to ponder 'supernatural'- few can do it, and therefore the original term was lost in society's framework built around it. Just like 'good' and 'evil', when analyzed absolutely, 'supernatural' can be seen in it's true light.
