The Maya civilization practiced a polytheistic religion, worshipping a pantheon of gods associated with nature, agriculture, and celestial bodies. Key deities included Itzamná, the creator god, and Kukulkan, a feathered serpent god. Rituals often involved offerings, ceremonies, and the use of sacred sites like pyramids and temples to honor these gods. The Maya believed in an intricate relationship between the spiritual and physical worlds. They held that the cosmos was divided into three realms: the heavens, the earth, and the underworld, known as Xibalba. Ancestor worship and the importance of maintaining balance with the gods were central to their religious practices.
