What is evolution’s explanation for man’s survival after he gained knowledge that he is mortal? I mean, when that first creature along the evolutionary chain realized that one day he too would drop dead, why didn’t he just pack it in then and there? It seems to me that the idea of a God had to emerge pretty damn quick at that point or else evolution would have hit a wall of suicide. Or they would have starved to death because they were too depressed to grub for roots in their existentialist funk.
