As far as I can see, Goddidit always remains a possibility, but it remains a possibility with zero explanatory power, and so zero usefulness.
I'd go farther than that. I'd say that, without a functional definition of the word "God", Goddidit is not only a useless explanation, but a meaningless one.
Actually, I
just went through this on another thread. An explanation that fails to explain who, what, when, where, why, or how really isn't an explanation... just a synonym for "I have no idea."
