Jason: The first person who came to this planet, how were they alive?
Me: Well, you know what Apes are right? Well there were apes, and then a group of them moved away and over a long time they learned how to cook and make fire and make sounds and pictures to let others know what they were thinking - they were cavemen. Those cavemen over time learned to speak and write and make more inventions and they became people.
Jason: Oh yeah, that makes sense! There was no first person, just cavemen!
Sydney: Why on Valentine's Day do we give out candies and other sweets?
Me: Because Valentine's day makes us think of our sweethearts and we want to give sweets and treats to our sweethearts.
