So they believe there's a God, but don't believe in a heaven/hell? They just think your life on Earth is your only life? I'm a Christian and I believe in the Bible, but I don't disagree with other religions. In fact, what pisses me off is that (in my religion) anyone who doesn't believe that Jesus died on the cross goes to Hell. So Jews would go to hell. It pisses me off because who am I to know which of the many religions is the correct one, if any. I'm only a Christian because I was raised that way. If I was raised Muslim, I'd be Muslim, and probably be that way for my entire life. I believe what the Bible says, but I don't necessarily disagree with anyone else's belief. Even the belief that there is no God.
