I think the film 'The Book of Eli' is a depressing reminder of what would happen in principle; even if religion, in this case Christianity, had been the ultimate cause of a world war and nuclear holocaust, some numpty would come along and try and save the last remnant of that cause, in this case the Bible, thinking it to be the most beautiful and precious thing ever created. And the cycle would start again. In other words, religion is going nowhere
