A strong case can be made that life is about replicating life. The grand design is that all reproduce, give birth to new life, and that each succeeding generation do the same, so that your name, bloodline and species will multiply, flourish, and most importantly, never die.
The great promise of many religions is that you will gain eternal life, that by believing such and such, by calling God by His correct name in the correct manner you will live forever, as will your friends and family, who will multiply, flourish, dwelling forever in a happy place, and most importantly, never die.
In this way religion is the logical outcome, even the perfection, of evolution. Belief in eternal life is not surprising but inevitable.
