The point of life is, technically, not to live, but to reproduce.
Why worship god? Just because he created all of us, is that good? Sacrifice for him? Die for him? Let him kill off as many of us as much as he wants, just cause he created him? Believing in good/bad is basically facism, only since that's the norm, it isn't.
The normal man that lives, has fun, marries, has kids, grows up, and then dies in a bed( or on a bloody, bloody field after chopping off a couple heads and then seeing those half nekkid war chicks swoop down on you for you vikings out there), he needs no philosophy. Philosophy is basically a recommended waste of time that makes us think and divert us form the main goal of life: Reproduction.
EDIT: Sorry, I meant, just because he created us
