“Consider the idea that nature itself is the product of design. How could this be demonstrated? Nature, as we have seen, provides the basis of comparison by which we distinguish between designed objects and natural objects. We are able to infer the presence of design only to the extent that the characteristics of an object differ from natural characteristics. Therefore, to claim that nature as a whole was designed is to destroy the basis by which we differentiate between artifacts and natural objects. Evidences of design are those characteristics not found in nature, so it is impossible to produce evidence of design within the context of nature itself. Only if we first step beyond nature, and establish the existence of a supernatural designer, can we conclude that nature is the result of conscious planning.”
Can anyone please explain what Smith means by this excerpt please?
