"Why does it happen?" Diana thought for a moment and then looked back down at the ground before picking a stick up. "Okay, this is our planet," she said as she drew a circle in the dirt. And then she drew a sun and a little moon. "So the moon circles our planet and we in turn circle around the sun, but our planet also rotates around and that's why we have night and day... Does that make any sense so far?" She wasn't even sure if she was explaining it in a way that made sense.
