Bedtime astrophysics.

Mom, why does the earth orbit the sun? Why does it tilt on its axis? If it's winter here, is it summer somewhere else? Are there other planets like ours? What are we made of? Where did we come from? How come some animals have babies and other ones lay eggs? When did that happen? How did the air get here on the earth and why doesn't it float away? How can the earth orbit the sun because of gravity when there is no gravity in space? Are you getting tired of my questions? No? Ok, goodnight.
