That organized matter operating under predictable laws will be found.
You just got through saying that a thoroughly hoc theory (one that can account for anything) is a good theory, and now this? Parading an arm waving generalization as a testable prediction, and a presupposition common to all scientific theories as the implication of a particular theory (ignoring for the moment that ID isn't a theory)?
Seriously. Are you purposely engaging in some sort of satire?
A good theory explains the data. When organized matter is found to behave in accord with predicatable laws, then it is reasonable to attribute this to intelligent design. What is intelligent design but taking matter and then organizing it to behave according to predictable laws?
Testable predictions are largely the practice of emprical science, when, on a smaller scale, hypotheses are formed and tested. You are mistaking "theory" for hypotheses. "Theory" is merely a general way of explaining the available data, so intelligent design makes for a very good theory.
Are you saying it is not possible for science to test for the presence of organized matter that behaves according to predictable laws? Perhaps the theory of intelligent design is so self-evident you have tired of it and yearn for something new. Be my guest. But don't think you've "explained" something any better when you assume and conclude that only "natural" causes can be explored by science. You tell me the testable hypotheses that can explain the presence of organized matter that behaves according to predicatable laws while leaving intelligent design out of the picture.
