is "goddidit" always an already presumed option when discussing evolution related topics?
Depends on how low a bar you're willing to put for acceptable explanations. In order for "goddidit"
ALWAYS be an option, you must bring that bar so low that other possibilities will inevitably leak in. Such as Last-thursdayism, Spaghetti-monsterinsm, and, yes indeed, (Invisible-)Pink-unicornism. And who wants that??
