Nobody seems to trouble themselves over the question of why Good happens.
Evil appears to require explanation. Good is taken for granted. I regard this not as commentary not on the gods but on humans. We assume good is natural. Good is unforced. It happens continuously, if unopposed by other forces. So it's Evil that requires explanation.
This means that human beings are naturally good. Not, I hasten to add, a positive good in the sense of going around doing Good Deeds; rather, a neutral good, a sort of generalize benign attitude and behavior that does no harm intentionally, though I think most of us think that kindness is also natural.
The view of humans as essentially sinful or even merely flawed or incomplete, is profoundly disturbed. It is a deliberately perverse view of human nature that cannot find anything better to do than to invent some impossible ideal and then blame us for not measuring up to it. Original sin is in this view quite a trick, for it places an unforgivable sin impossibly out of reach or hope of correction. It's as if we all of us raised our children repeatedly blaming them for something they never did and cannot amend.
The atheist is not compelled to explain Evil any more than he is compelled to explain Good. The only task before the atheist is to explain Human. And that is challenge enough.
Still smilin'
