Muisca astronomy refers to the way the Muisca civilization, who lived in what is now the country of Colombia in South America a long time ago, understood and used the sky and stars.
The Muisca people believed that the world was divided into two parts, the upper part where they lived, and the lower part where dead people went. Up in the sky, they thought that there were many different gods and spirits that controlled what happened on Earth.
The Muisca also studied the stars and constellations in the sky, much like scientists do today. They kept track of the movements of the stars and the changing seasons by following the phases of the Moon. They noticed that, as the Lunar phases changed, the weather also changed, so they came up with a system to predict weather based on the Moon's appearance.
One way the Muisca used their knowledge of the sky was to navigate. They didn't have maps or GPS, but they could guide themselves through the mountains and forests by observing the stars, much like modern sailors use stars to navigate on the open sea.
Overall, Muisca astronomy was a way that the Muisca people understood the world around them, including the sky above. They used their observations to survive and thrive in their environment, just as modern people continue to do today.
