Ha! To think that religion is primarily about death, especially because "humanity is programmed for it" is to get the whole concept arse about and backwards: It's a small subset of culture with specific influences.
Jebus, we really, genuinely, honestly are obsessed with sex and what results from it more than anything else. You want a connecting thread in religions, look at that! There's so much about the regulation of it, the suppression of it, the encouragement of it, stuff about progeny, ancestry: all about sex and children. That's what we're really obsessed over. And that's renewal. In fact most religions in their earliest forms have much more focus on "mother Goddess" figures, births, and planting times. :)
And all that is entirely the focus of this subject. Lothar talks about the world ending. I say that people only think like that because of certain specific cultural influences, -that are especially popular right now, just the same as they were after the first millennium had just passed. And then I've gone to prove why that's so.
Truly. Your world will end, but only when you do.
Guess we're going to have to disagree.
Religion IS obsessed with death and the end of the world. The end of the world takes up an entire book in the New Testament. The premise of most religions is that you follow a rule set in life so that you are rewarded in death. Without death, the religions have no meaning. Without death, people wouldn't care about the consequences religions tell them to care about. When Adam and Eve took of the tree of wisdom, their punishment was mortality. What did Jesus have to do to save the rest of us? DIE. Yadda yadda yadda. Religions are quite focused on death. Believers in reincarnation tell us that you are reincarnated in the form that rewards your previous life. Eh... I could go on, but you get the point.
