FAQ #Dust of the Earth

"If the atoms that make up each human being came from the stars, why does Genesis say we came from the dust of the earth?"

In the book there's a point about different ways of looking at people being made from dust, one of which is that our food comes from the soil and dust of planet earth, we eat the food, the food becomes us, so we come from dust too. Okay, but what about when we eat fish? Fish eat other fish!
