I was reading a Buddhist discussion on rebirth (How do Buddhists deal with the idea of rebirth?) and found a comment I really liked (not quoting):
You don't survive death because the "you" that you think you are doesn't really exist. Why would a construct in your mind survive death?
Another good point in the discussion: the "rebirth" concept is mainly metaphoric - to really live every moment, you have to die every moment, and be reborn.
