By her consort Anu (also known as Anunna), Ki gave birth to Anunnaki; the most prominent of these deities being Enlil, god of the air.
[3] Some authorities question whether Ki was regarded as a deity since there is no evidence of a cult and the name appears only in a limited number of Sumerian creation texts.
Samuel Noah Kramer identifies Ki with the Sumerian mother goddess Ninhursag and claims that they were originally the same figure.
[3] She later developed into the Babylonian and Akkadian goddess Antu[citation needed], consort of the god Anu (from Sumerian An).
In Akkadian orthography, it functions as a determiner for toponyms and has the syllabic values gi, ge, qi, and qe.
