No, it's not. You haven't addressed the max.toe diagram (or other similar
scholia) which certainly seem(s) to show that Hal's summary statement is
correct: *life as we know it* can't exist in most plausible universes. God
is a blind alley in this discussion, or at least just one kind of (sheaf
of) possible explanation(s) for the life-cosy character of the universe.
Either we live in one of an indefinite number of variant universes, or this
one has been built with life in mind, or life is an unsurprising side
consequence of cosmogenesis. Whatever is the case, it's a genuine puzzle.
