I don't want to be borring or to upset somebody, I just surfed in, and feel like talking about. But we really don't want to if we can help it. That is why we hang on to the belief that God does indeed exist and we will continue on after our physical death. It is necesary for us to believe in God, we may protest that we don't, but deep down we hope we are wrong. Most people who are alive, I think, have a rather hard time imagining or even wanting to stay alive forever.
Real existence is too tiresome and confusing to put up with on that basis.
It seems that life, like all natural things should eventually have an end. But when a friend or loved one dies, it becomes very hard for the remaining community to believe that good old Uncle Harry or Joe is really gone. So the idea of an after life was created in ancient times out of a kind of respect for those beloved who had departed. Christianity merely corrupted this ancient benevolence and turned into a selfish wish for personal survival in some glorified super state and threw in the idea of God as the grand underwriter of the whole scheme. But it is all fictious.
