You are right Dawkins does not know but he admits the appearance is design. Does a natural, uintelligent process design things ?
You have no positive evidence for a designer. All you have is: it looks designed because that is familiar to us, because we have the capability to design things our own things, and compare what we design to the universe around us, and conclude that the universe was also designed. Our ability to design and implement technology and any similarity those technologies have to the universe is not evidence of a creator by a long shot. It is a biased perception based on our own capabilities as a species to design our own tools, technologies, which is merely an emergent and evolving property of our intellectual ability, which is a product of evolution, a natural process without design.
The appearance of a designer does not mean a designer necessarily created it. That is a subjective judgement, whether something has the appearance of a creator, so in a sense is a circular assessment. You already assume there is a creator, and then look for it in the universe, and anything that resembles order seems to validate your premise that there is a creator, hence you conclude there is a creator. That is circular. You have to take out your presupposition that there is a creator in your premise, then you can see the universe from a neutral standpoint. I don't think you are willing or able to do that. This is the problem with theologians. It seems as though their premise with respect to the universe subconsciously always contains God, and so they can never assess scientific claims on their own merit, because it always contradicts their premise, and so are merely always trying to contradict or disprove science as a way to vindicate their premise. I see this more as a psychological need to keep their belief system in check, because beliefs largely inform our identity, and their destruction is scary. Science threatens creationists, so they desperately find ways to counter it, however, they use illogical arguments because their need to do this is emotional, not logical. This is my opinion, obviously. Hence, the issue is psychological, not philosophical.
