Everyone need some type of beliveing to give them comfort and reasurance. I belive science, straight science. Once your energy running throughout your body dies, all of your memories, thoughts, knowlege, almost exhistance does too. Other people can sertainly keep your exhistance true by remembering you. Kind of like in The Forgotten. When someone dies instantly and painlessley, if they had a great life then it is no loss.
Energy is literally everywhere. It is neither lost created or destroyed. I think this whole livable atmoshphere, all evolution came to be this way by chance, sparks of energy. This is why I love storms, when all the energy is shaken up. I saw an interview about a man in Scotland that slipped on the ice and fell on a stake. It went through his head, but missed everything by fractions of inches everywhere. What were the chances of that? I think something like more than winning the lottery and getting striked by lightning in the same day. If this could happen, then I see no way the universe and all things could have formed to be so perfect if these chances and sparks didn't happen to happen whenever they did.
