There you go again. As I said, you simply reject ID by fiat because you don’t like its religious implications.
And what does “study of the designer” have to do with it? Science is the study of the design, not the study of the Designer.
The distinction here is very simple. Suppose someone sends you some software, and you have no clue who wrote it. Would you claim that it was not intelligently designed because you know nothing about the designer? I hope not. But that is the logical equivalent of your nonsensical claim.
No, but I would believe that whoever ran the that software on the their computer whould lack intelligence. In a similar manner I would attribute to any scientist a similar lack of intelligence if she decided that something was so complex that only God could have put it together and thus stopped searching for the truth.
