Do people believe in religion mainly because of the incentive of immortality? Because as I look around me, many theists today say they believe in God and are "religious", but are anything but the sort. So, the only conclusion I can come up with is that these people are simply scared to die. They(or anyone else for that matter) don't want to become annihilated when they reach death, they mearly want to continue on living. So desiring other peoples' input, is this the only reason why people choose to believe in a higher power these days?
I don't think animals, even apes, fear death. They may fear something, but death is a concept humans hardly understand. It involves thinking of a time when the thinker will be absent from the scene. I just can't imagine animals thinking like that. Animals are all "in the moment."
