Genesis, according to my son

"Long long ago, before their were people, there were dinosaurs. And before THAT, there were superheroes, and supervillains. And the supervillains wanted to destroy the WORLD, and the superheroes stopped them and THAT'S how the earth was made. The green blood made the trees and the brown blood made the dirt."

"But humans made this house. A long time later."

Clearly I have some work to do on his edu-ma-cation.
