Read a very interesting opinion article on CNN last night. "Why I raise my kids without God".
The writer aluded to the fear of the possibility of one's life ending forever (along with our beloved children's). Thus, necessitating God whom embodies the concept of life and eternity. Those of us who believe in God (real or not) can psychologically cope with death in other words.
That fear of absolute 'finality', is it really predominant? For those who are atheists, how have you come to accept non-existence?
