The main problem with ID is a complete inability to predict or discover anything at all.
You can apply post hoc interpretations to anything. And this is exactly what IDists do to the verified predictions and discoveries that genuine science achieves.
Is ID capable of making verifiable predictions and discoveries? Is ID "science" able to demonstrate itself as able to meet the same exacting standards as genuine science? Rather that simply asserting that all interpretations are equally valid?
What has ID science ever discovered? And if the answer to that question is "nothing" how can it claim to compete in terms of the validity or accuracy of it's conclusions with conventional science?
