Funny how indirect evidence suits the purposes of science in every case except when it points to intelligent design. Why the blind spot?
What does indirect evidence have to do with it?
The reason ID is not considered science is because of the difficulties inherent in knowing the design status of an object when nothing is known about the designer. It does no good to have as many false positives as correct results. Get the people at DI to fix the problems with ID then talk about getting it into science.
