What was Inca's religion like?

The Inca religion encompassed three realms of deity worship: Hanan Pacha, which is the celestial realm in the sky; Uku Pacha, which is the inner earth realm; and Cay Pacha, the outer earth realm, where mankind lives. There were several polytheistic religions in the Incan empire but they all contained these three main points or common themes. This helped the Incans bolster their faith and the strength of the empire when they conquered other people and absorbed their religious pantheons.
