Clara: Why do we live on Earth and not one of the other planets?
Me: Earth is the only one with oxygen. We wouldn't be able to breathe on the other planets.
Clara: But there is some oxygen in space.
Me: No, when we go in space we can breathe if we are on a spaceship or if we have an astronaut suit that keeps the oxygen in. But there isn't oxygen just in space by itself.
Clara: But some galaxies have oxygen.
Me: No, not to breathe. Not that we know of.
Clara, getting annoyed: Mom! You need to just say "I don't know about space!"
