When I was a child, I had a great many misconceptions about the world.
You know how scientists say the dinosaurs died out 65 million years ago? Well, about a decade and a half ago, at the turn of the New Year, I turned to my mom and said, "Well, I guess the dinosaurs died out 66 million years ago now."
I also used to think that the sun was in the Earth's atmosphere and that baby sheep were called sheeplings.
I'm still not entirely convinced that last one isn't the absolute truth.
