can't you envision an alien culture that is so far advanced from us that they no longer have wars or the need to rape other cultures for their resources . Maybe we could even get there ourselves, but without "Divine Intervention" I'm pretty sure were destined to self destruct. Maybe it's like "star trek" and there are waring clans all over the universe, although you must realize these theorys were propagated by a human and we all know how fallible they are. Can you imagine a planet where the condition of the majority of the inhabitants live in worse poverty, have more wars, more animosity towards one another, more self-importance and less caring than this one, I believe that would be called Hell! There are a few good human beings on this planet, I don't think there are enough to stop the madness. Nuclear holocost is inevitable. Man has never made a weapon that he has not used extensively, Hiroshima was a drop in the bucket!
