Bedtime stories are getting more advanced

This evening's discussion was mostly about different rovers that have been sent to Mars, both successful and failed, and what some ideas are for colonizing Mars in the future. He asked me why the Earth spins... And I don't have a good answer yet. I told him its probably because it's being pulled by the Sun's gravity but that probably isn't right. I'll have to have a good explanation ready for him tomorrow.
