And NC, at least they have something to hope for, someone to hope IN. What would you give them? Oh... that is right: 'realism'. (your version of it, at least)
I would make up a story about a loving god that takes care of those he loves. I'd tell them about times that I was hungry, and how this god came to my rescue through those that love him. Maybe I'd tell them about my home and my education and give this god credit for giving that to me. I'd explain that perhaps they should pray, but don't expect results. It's up to the humans. This god I love so much is soo very powerful, but he has chosen not to feed them, because some humans are bad. I'm pretty sure they will understand when I tell them about the atrocities that Adam committed. I'd tell them to look forward to Heaven when all of their pain will be washed away, and I'm sure they will then hope to die.
Then I'd share my sandwich with them and tell them about this wonderful Christ that fed thousands of people with just a few loave and fishes. But those were more important times, and more important people. They had gone maybe the day without food, and really, needed their bellies to be filled so they could focus on his speech. You understand, Little One, Jesus isn't on earth anymore. In fact he is in Heaven and even MORE powerful, but he doesn't feed people anymore. That's up to us. You should get to know him---you'll be seeing him soon.
