Kaitlyn and Arianna were looking at their "space" book. Kaitlyn was being the "teacher" and showed Arianna the different planets (she's still working on learning their names). She pointed to the sun, the moon and then picked out Earth and said "this is Earth that's were we are from". Arianna replied "Cool! Where are the aliens from?" LOL. I love listening in on their conversations, it's always amazing what and how they process things.
