The Mayans were also astronomers

Good point, cutworm!
When you think about it, in 2024 we spend almost no time outside at night gazing at the stars/sky.
Most of what we know about astronomy we got from books, using pictures in books and science explanations from really smart people that figured it out for us.
In that age, they had their eyes/brains and direct observations that were all the time in their lives.
Most people didn't have any idea that the moon was 400 times smaller and 400 times closer than that sun, which is why they appear to be exactly the same size in our sky(a fact that has always blown my mind).
And that the stars were light years farther away. They thought that much of it was in the same plane in the sky and it all rotated around the earth, which was the center of the universe!!!
