Atheist parents have to get past questions of death too.
This is just off the top of my head, but... "Being dead is just like going back to what it was like before you were born. You don't need to fear all that time before you had been born, nothing bad or scary happened, so why fear what will happen when you die? Every time a child is born, they are just one out of billions of possibilities, all unique, just like you and me. But the planet can only support a few of us at one time. We're lucky right now that we get to take our turn, but we can't be selfish, and claim the earth is our's forever. We have to give some of those other unique people a turn too. We have to give up our seats so that our children who we love so much can have their turn. If we're lucky, maybe we can do something now so the world is a better place for our children."
Compare with:
"There might be an invisible man in the sky that watches everything you do. You know what his favorite game is? Musical chairs!! Except when the music stops, if you don't get a seat, he kills you with fire, plauges, and giant holes in the ground that'll swallow you up. You know what the best part is? He makes the game even harder! Not all chairs are equal - most of them are decoy chairs! So even if you find a seat, it might not be good enough. Now, I'm assuming based on a 'good feeling' that of the thousands of potential gods, the chairs for christian gods are less decoyish than the others. Of course, most christian chairs are decoys too. You have to look really hard, and even then it might not be good enough. You have to pick the right religion, sect, and then, you have to spend your whole life hovering over the chair, making sure you never do anything with your life that might bring any distance between you and the chair. That is what life is about -hovering your butt over a chair waiting for the music to stop. 'Cause if you don't, the invisible man in the sky is going to hate you and burn you with fire."
