Incan mythology is fundamentally structured around the deity Viracocha, who is considered the creator god. He is responsible for the creation of the world, humankind, and the sun, moon, and stars. The narrative often emphasizes themes such as the importance of agriculture, particularly the cultivation of maize, as well as the connection between the people and their environment. Viracocha also plays a vital role in Incan cosmology, where he embodies the dual forces of creation and destruction, illustrating the balance necessary for sustaining life. The mythology reflects the spiritual and cultural values of the Inca civilization.
