All religions promise the same concept of a heaven after death. Some claim a paradise, others outer space on far away planets (Mormons), but they all claim a heaven like paradise where they will live for eternity. Some even claim virgins will be there which implies that heaven for men, at least for straight men, is having a whole lot of sex.
Death is a mysterious and terrifying reality that everyone must come to terms with. The majority deal with death by believing a fairy tale. Religions are selling an invisible products, a way of living, a code of ethics, an imaginary boss, and an afterlife.
