Why do you feel that is a worthy goal? It just seem like hubris to me. Of all the life forms on Earth, only this current version of humanity is worthy of immortality? To me, thats just a coping mechanism people use to mind trick themselves into feeling they arent mundane, arent alone, arent going to simply die and be forgotten by history, but will in fact live on for all of time. With that basis in mind, religon can then backfill in a bunch of stuff to influence peoples behavior.
