Note: The objections of David Hume against arguments from design (Paley's watch) have been undermined and invalidated by advancements in biotechnology and other technological and industrial fields whereby systems and organs in living things are studied, analyzed, reproduced and mimicked in order to provide solutions to problems. The gap between technology and biological systems is closing as time progresses which proves that objections such as "living organisms are unlike objects manufactured by humans" are fallacious. On the contrary, the evident design inherent in all living organisms is being drawn upon to gain ideas and understandings to aid in the design of more sophisticated, smart and efficient machines or technologies.
Might be a good idea to read this article first (Ibn Taymiyyah on the Reasoning of the Atheist). Statements of some atheists in relation to design: Richard Dawkins writes, "Living things are not designed, but Darwinian Natural Selection licenses a version of the design stance for them. We get a short cut to understanding the heart if we assume that it is designed to pump blood" (The God Delusion, p. 212). Living things are categorically 'not designed' but you get 'short-cuts' to (scientific) understanding by assuming things are 'designed.' Such sophistry, double-speak and arrogance in one sentence. All scientific, technological and industrial activity has to assume actual design, order and regularity in life and the universe. Jerry Coyne writes "If anything is true about nature, it is that plants and animals seem intricately and almost perfectly designed for living their lives" (Why Evolution is True, p.1). Michael Shermer writes, "The design inference comes naturally. The reason people think that a Designer created the world is because it looks designed" (Why Darwin Matters, p.65). Note how these atheists cannot deny design, and it is only because of a prior metaphysical belief in naturalism, materialism that they portray it as being "illusory" and only "apparent."
The inference from design to designer is innate, logical, rational, and totally warranted. It is why you see these Atheists on the tips of their toes, making very carefully crafted statements like those you read above - design is there, but they have to make it go away. How is that done? Assert a metaphysical belief in naturalism and actual design (by any standard) can then be treated as an "illusion of design", why, because naturalism is true. However, despite this swindle, researchers have a hard time trying to understand why even Atheist professors cannot avoid teleological language (consciously or subconsciously), let alone those less-educated than them (read about it here). The story below is just one illustration of thousands of similar ones that could be given (in the field of technology and industry) to demonstrate why it is that no matter how much brainwashing and propaganda is employed to convince people that "nothing creates something" or "matter self-creates and self-organizes" there is within each soul a pre-programmed innate ability (fitrah) to recognize and accept certain universal truths and to be averse to purely material explanations of life. This innate default can be difficult to undermine, and it is the basis upon which the Prophets and Messengers made their call, to corroborate this universal truth and to complete and perfect what this innate disposition necessitates in belief, speech and action.
