Skywatchers

People have been wondering about what they see in the sky for a long time.

Because of our curiosity about the sky, we tell stories and myths about what we see there. The desire to explain what we see around us in the simplest way using science has driven astronomers for centuries.
By carefully watching the sky, astronomers learn about how the universe works.

And so we see that even the earliest man would have watched the day and night sky.

It is these people who were the Natives of the Americas. They too watched the sky. It is interesting to look at evidence of that skywatching by looking at the ancient astronomy practiced by the Native Americans of North America, the Maya of Central America and the Inca of South America.
