The Anunnaki (Sumerian: 𒀭𒀀𒉣𒈾, also transcribed as Anunaki, Annunaki, Anunna, Ananaki and other variations) are a group of deities of the ancient Sumerians, Akkadians, Assyrians and Babylonians. In the earliest Sumerian writings about them, which come from the Post-Akkadian period, the Anunnaki are deities in the pantheon, descendants of An (the god of the heavens) and Ki (the goddess of earth), and their primary function was to decree the fates of humanity.
