Luke, the wunderkind over at Common Sense Atheism, continues to be a tremendously salutary voice in the online conversation about God. Recently, Luke set out to kill a sacred cow, "one of atheism's most popular and resilient retorts", namely: "Who designed the designer?". This, he argues, simply is not a defeater to theistic arguments. I should add, what he offers with one hand, he takes with the other. "The problem with offering 'God did it' as an explanation is that such an explanation has low plausibility, is not testable, has poor consistency with background knowledge, comes from a tradition (supernaturalism) with extreme explanatory failure, lacks simplicity, offers no predictive novelty, and has poor explanatory scope." But returning to the more common objection, Luke points out 1) that we accept unexplained explanations in science, and 2) that if every explanation must be explained to count as an explanation, we end in an infinite regress and nothing is ever explained. It is the nature of the case that some explanations must be ultimate explanations. Both of Luke's points are well taken, and echo the responses offered by William Lane Craig and other theists to this common rejoinder. However, throughout, Luke characterizes the supposed conclusions to the natural theologian's premises as simply: "God did it". Luke undoubtedly knows that this is an oversimplification of such arguments when they are carefully articulated, that much like postulates in physics, their conclusions are of the form: some entity x exists with property p. We'll give it the name y. I do not mean to nitpick, and I understand the use of shorthand, but this distinction is critical in evaluating the appropriateness of a given explanation, the very subject matter of the post. My attempt at a constructive response follows.
