I don't care about Behe, I mean the concept as a whole. By that I mean, do you not believe there is anything that exists in this world which is difficult to explain with "it randomly mutated until it became that way"?

I don't care what people invoke (brain, eye, bombardier beetle, etc). I'm saying that without understanding the full nature of something, you cannot claim to understand its origins - I chose the brain because its undeniable that there are aspects of it (savants, autism, etc) which are still big question marks for us.

I think evolution is undeniable, to some extent. However, I think its a piece of a larger puzzle which we are still piecing together.
