In my opinion questions such as who was the designer and who designed the designer are only important after design has been detected. In fact this is how many branches of scientific endeavor must proceed. Ask any detective at a crime scene, do they ask who was the murderer before answering the question of was any murder committed in the first place.
There are two separate questions (1) was there design and (2) who was the designer. It really is a common sense observation that the second question is logically downstream from the first. It is a corollary to that common sense observation that anyone who insists that one cannot address the upstream question until one has resolved the downstream question is either deeply confused or has an agenda unconnected with discovering the truth of the matter.
