Atheism and the meaning of life - what drives you?

[Ahriman]

What does interest me is how there can be any "meaningful" relationships in the sense of warranted correspondence between our semiotics-based understanding of the world and physical reality.

Without the resurrection+, life doesn't have any meaning. Atheists are content with death having the final say. However, everyone is resurrected, adjust to it. 

Well, there's a christian answer for you Neo.  There is no meaning to life.   Whatever value worth or meaning it has is given to it by some other thing, some afterlife.  One wonders why or how an afterlife would have meaning, or grant meaning to life, if life has no meaning itself, just another christian mystery.

The next life will be better than this life. That should come as a relief to many people.
