What did the Mayans believe about the earth?

The Mayans believed that the Earth was a flat plane, often depicted as a giant turtle or serpent, floating on water. They viewed the world as a layered structure with the underworld (Xibalba) below, the terrestrial realm in the middle, and the heavens above. This cosmology was deeply intertwined with their agricultural practices, calendar systems, and religious rituals, reflecting their understanding of cycles in nature and the importance of maintaining balance in the universe.
