I'll give you a hint:
The first known person to claim to be a god in Mesopotamia is the first person who's name is signified in literature with notation for divinity
In turn this same person standardized all measurements in Mesopotamia for several thousand years
Basic Bible history here
Quoting: Anonymous Coward 27255788 The person would be Naram-Sin, grandson of the founder of the Akkadian empire
He's the first known person, by our records, to have claimed to have been a god on earth
Also the first to use the title " king of the four regions "
The notation is the Akkadian cognate to the semtic " El ", it's called the " dingir "
You may know this as " An " ( like anu, Annuna , annuna-ki )
so that's the answer, it's just a generic word for a god
but this notation is far older than Naram-sin's use
It's the Sumerian pre-cuneiform ideogram for a star
So there you have it
The origin of the titlo is the
Sumerian ideogram of a starNow you know why the Bible uses the phrasing like "
star in the pit "
