The Anunnaki are a group of deities of the ancient Sumerians, Akkadians, Assyrians and Babylonians.
Abraham, the jew on which all abrahamic religions are based, was sumerian. Therefore his "god" is the main Anunnaki deity, An.
This is the Anunaki pantheon and its Abrahamic rebranding:

>An = Yhvh
>Enlil = Lucifer
>Enki = Jesus
>Nanna = Al Lat or Allah
>Utu = Satan
>Inanna = Mary
