Explaining Death

Breanna asked me if I had any Papas. I said, yes, but they're both in heaven now. She wanted to know how they got there - not what allowed them to be there, but physically how they got there. I said, trying not to scare her since she just got over being sick, that they were old and they got sick and their earthly bodies just quit working. So their spirits went to heaven to be with Jesus. This seemed to satisfy her, since it sounded better than her idea:

"Did they just disappear like magic? Or melt or something?"
