What caused your comment above to appear on HN?

Because youdidit.

That's not an explanation?

There are different kinds of explanations according to different measures, but all explanation is about identifying the causes of things. "You did it" identifies the agent, the efficient cause. I can, of course, explain how the agent (you) effected the cause, but youdidit is still an explanation, even if it isn't the kind you are interested in hearing.

Youdidit is an explanation, because it doesn't terminate the inquisition. You can then ask what caused you, then what caused the thing that caused you, and so on until you get to the point of saying "and that's as far as we know, we are working on figuring out the rest".

With goddidit, you abruptly got to the end through an escape hatch, and you are done having done no work. There is nothing that explains god, by definition, and there is no "figuring out the rest".
