"I suppose there are closet atheists, though I have no way of knowing."
Not really, mlcnnnn. We atheists already checked the closets, and didn't find any deities in there, either. A goblin or two...they're useful for frightening children, but no deities.
We're still looking in various places, but most common places a deity might hide out have been examined already.
Well, MM, don't give up the search. Better yet, let God find you.
