If there was an objective meaning of life.
As a 36 year veteran of a subjective existence the only thing, at this precise and exact moment in time, that i know for a fact is conciousness (my conciousness) is everything!
So to the question (which is a hypothetical one) "if there was an objective meaning of/to life, what is it" ...... probably everything ever done, said, created, destroyed etc etc....
For me it is quite simply gaining a higher conciousness. If we are in fact gods then i will do everything my conciousness allows to be a better god than the ones we all have been taught about.
