Startingover,
(My personal opinion only!) I think that people need religion to stay sane - to realize that ultimately, there is nothing after this life. NOTHING. Some people I have met through work (not friends of mine!) have openly said that they would be horrible people if it wasn't for god. I don't need to believe in god to be a good person - to not go out and kill people. To be a good person - to contribute to society. To not go out and kill cats for no reason - you know what I mean,.
In any event, even I don't ultimately know what will happen when I die. I'm pretty sure I won't be floating around the clouds, or burning in hell. It will be quiet and dark.
