Is Intelligent Design Being "Expelled" From Scientific Thought?

Ben Stein said that intelligent design is "the hypothesis that life did not originate randomly -- not by random mutation and natural selection -- but that there was some design involved by an all-powerful designer." (See "a discussion between R.C. Sproul & Ben Stein about evolution, and the movie Expelled: No Intelligence Allowed," http://video.google.com/videoplay?docid=-4609561480192587449&q=Expelled%3A+No+Intelligence&ei=-csSSNigCZDCqAP65aDFBA ) Mr. Stein's definition of intelligent design contains a refutation of natural selection. I believe that this practice is anti-scientific. A hypothesis should include assertions about what did happen (i.e., "A" caused "B"). If Mr. Stein's intelligent design hypothesis is put into a cause-and-effect format then intelligent design becomes the hypothesis that an all-powerful designer created the ancestors of the forms of life that exist today, and that those ancestors were not significantly different from their living descendants. When Mr. Stein's hypothesis is properly stated, it becomes clear that his hypothesis cannot be verified and cannot become a scientific theory.
