Typically, when someone's car breaks, they don't bring it to church, they bring it to a mechanic. In the distant past, people probably brought the equivalent of their cars (when broken) to the equivalent of church. This is progress. I could be wrong, but I think Luke wants more of this, in more domains. I personally think this is less a question of the right explanation, and more a question of daily necessity. If you need physics every day, you'll have fewer wrong ideas about it. But who needs physics every day? Almost no one.

(And yes, some people probably still bring their broken cars to church.)

EDIT: Not everybody wants to be or has the talent to be a "mechanic," but that doesn't matter. What matters is that people associate "broken car" either with "person who can fix broken car" or "reliable knowledge about how cars work" instead of "sky father."
