Dawkins claims scientists, not theologians will inform us about the formation of the universe. The supernatural adds nothing as Aqunas' superfluity , the Ockham and the presumption of naturalism note.Percy Bysshe Shelley implicitly use the superfluity argument in noting that " To suppose that some existence beyond, or above them [ the descriptions- laws of Nature,M.L.] is to invent a second and superfluous hypothesis to account for what already is accounted for>" To insist that why, that's a category mistake begs the question thereof.
Dawkins explains in his books how natural causes without boss God makes for transformations of living things. No divine intent necessary to explain how natural causes operate.
Stenger notes how the laws of Nature need no boss to operate, and I add, He's depend on them as the primary cause, not Himself! The laws describe how matters work without involving any divine intent.
