Why did god make Noah build the ark? Couldn’t he just have MAGIC’D it into existence? Better still, couldn’t he have just voodood all the bad people away without any need for a flood in the first place? It seems a crazily inefficient way to go about things.
Of course, we rather need to ask why he allowed people to be bad in the first place. If the answer is to be “free will” then we’re not really much further forward. Give people free will then punish them when they exercise it? It seems capricious at best but the more parsimonious explanation is just plain incompetence. Why don’t biblical literalists ask themselves questions like this?
