Did you know that Earth is the only planet in our solar system with just one moon?
Moreover, that moon is at exactly the distance from the Earth to make it appear the same size in the sky as the massive sun, which is 93 million miles away? You can see this with a solar eclipse. How did this happen in just this way?
Except that's not the case. You wouldn't want to try to perform long-distance navigation with a 600 year old star chart. Where the stars are in the sky, at the same relative point in a year, has been changing, over time.
