And as for the religious idea of the concept of an afterlife satiating our instinct that the sole meaning of life is survival, I would assert that this is untrue in a universal sense. The religious are, for example, at base, focused upon death more than living in this life since earthly existence is merely a staging area for what comes after.
To put it another way, religion contains adherents who are strongly certain that death is an absolute requirement to reach a far more ideal, more pleasant and pain free place which humans were truly meant to inhabit and with little doubt.
Who among such a flock would not prefer the end of this life occur sooner rather than later, should they be genuinely convicted about belief in the aims and claims of their faith? How, then, does this align with interest in continued existence on any plane?
