All scientific theories explain a natural mechanism for observed physical phenomena.

The computer you're sitting in front of is an "observed physical phenomenon". Are you saying it's unscientific to theorize that it arose from anything other than natural causes?

Yes. 'anything other than natural' = supernatural. Scientific theories do not deal with anything supernatural. It is unscientific to theorize anything arose from supernatural causes. Man is not supernatural. The computer I am sitting in front of is man-made. You get the idea.

Now you realize that "supernatural" is your word, not the word invoked by ID theory. ID simply posits that the development of species was a result of some form of intelligent intervention. Nothing about it hinges on this intelligence being "supernatural" (a term with no clear meaning anyway).

I found http://www.designinference.com/documents/2005.06.Defense_of_ID.pdf very interesting, pages 8-11 deal with your objection very well. They argument boils down to an explanation of how science is currently locked in place to only use methodological materialism. The graphic of the chess board is telling.
