"The oracles at Sinai have to know this, because instead of being a god, Jovah is a spaceship." (Isabella has always told bedtime stories about spaceships, pretty much specifically to prepare for this revelation.) "Sometimes something goes wrong with it, and then it needs to be able to tell an oracle to come fix it. So Alleluia told me her secret, and I told her mine, and I went up to the spaceship, and it wasn't very smart at all. It could talk, but it didn't really understand things; it only did what the settlers told it to do, and what it heard prayers for. I didn't think it was doing a very good job of being a god, but all I had to do to make it listen to me was just a little bit of magic, and now I'm the spaceship's captain."
