If the mere interpretation of forensic evidence is what constitutes science, then why is it "unscientific" to interpret biological entities that function as machines to be the product of intelligent design?
Selection is not just a WAG. It implies many things and predicts many knnds of evidence that were not available when the hypothesis was first formulated. And many kinds of evidence not yet found. It predicted, for example, the minimum age of the earth at a time when physics was wildly off base. In short, it has survived 150 years of accumulated evidence.
