This question can up on Champy's blog.

" Q. So - why DO you think we should teach Intelligent Design, what are the scientific merits of it that bear    classing it into a theory with the same standing of evolution? "

May I say neither.

When you go infinitely small you get nothing. When you go infinitely big you get nothing. That leaves us somewhere  between the nothingness.Intelligence is something humans made up. Evolution is still working on making a connection between us and the chimpanzee but we will never know. We use our intelligence to make theory to explain it but there will always be questions as long as we use our intelligence to explain everything.
