Screw it. For better or worse, call me an atheist. Now, to the topic: Why does religion exist? Well, it is one way to explain the world around us. That includes death. It also sets a certain moral code a lot of the time, and enforces it through the carrot and the stick approach. People today are raised to believe in their religion, be it Christianity, Islam, Judaism, Hinduism, Buddhism, or anything else. Why am I an atheist? The idea wasn't reinforced over and over as I grew up. Now, what I find wrong is when religions use their influence to control people. Talk all you want about the love of God and of Jesus and all that, but then don't say that we are all sinners because the first two people on Earth ate apples, and because of that, we need to believe in God, pray to God, and go through all kinds of ceremony in order to get the carrot and avoid the stick.
Ah, but I'm ranting. Yes, religion gives us hope for life after death. Personally, I'm with George Carlin on that. Getting dead sucks either way, but no one would mind being dead. Then there's the moral codes and the sense of brotherhood and love. That's enough for now. I'll bash religion some more in other threads about it.
