If you're willing to grant the status of "science" to reasonable inferences based upon unobserved, unrecorded processes, then don't be surprised when certain folks who cannot produce an intelligent designer infer that one exists where organized matter presents itself, and call such inferences "science," too.
Actually, science can recreate conditions from millions of years ago and duplicate the results. That's science. ID cannot reproduce results. That's not science, or if anything that's a theory not able to be proven through science.
