I personally don't believe in heaven or hell in the normal "christian" sense, like if you're good you get to go to heaven and if you're bad god will punish you for eternity in hell. I really can't comprehend a god who would create life, and then turn around and punish it repeatedly. I also don't believe in a god who, perfect as he/she is, would create a being with the full knowledge that he would become evil and cause the bad things in the world to happen. It's just completely contradictory! I don't believe in the adam & eve story either; I think this was just a way for our male-dominated society to blame everything on women!
I truly feel that heaven is where you are happiest and where you get to go to meet with your deceased relatives and friends, then eventually begin again (I believe in reincarnation of the human soul), and hell is here on earth.
