I believe that Abraham was supposed to be in the 1800s BCE and the Sumerians were before 2000 BCE.>>>>>>>>>>
That is correct. The bible describes Sodom and Gomorrah as an incident from antiquity. The Jewish nation had not been even formed and the followers of Jehovah were in nascent stages, a minority within a larger pagan matrix.
The Sumerians recorded the event in their clay tablets , describing a war between the gods of heaven ( Anunaki) and the gods of earth ( Marduk et al). According to the story The Earth gods lost that battle and had to abandon the earth
and the civilizations they supported. Only Egypt and Babylon
survived with the memories of Marduk intact. It is after these gods abandoned the earth that the Supreme being Yaweh exercised a dominion over the entire world, and the Jewish culture solidified into the deep tradition we know of today.
The Sumerian legends say that 7 devices were dropped throughout the ME, destroying the human city/civilizations established by Marduk and his fellow gods, both male and female. They fled the earth, and some say one day they will return. Lets hope not, they have nothing but enslavement for humankind. Some today say that Allah is a remnant of the god Marduk and his entourage, not to be confused with Yaweh in any way, who is completely separate altogether.

If Abraham lived 175 years he could have lived from 2000bce to 1825 bce. He could have lived from 2075 bce to 1900 bce. Abraham was moved with his father from UR to Haran and then Abraham moved from Haran to the “land God showed him”. So Abraham could have see some of the destruction of the Sumerian cities or was moved by God to protect him and the “great nation that was to spring from his loins thru Isaac”
The Bible in Revelation describes two big meteor impacts yet to come...as well as “wars in the heavenlies” with Satan and his angels thrown down and locked out of Heaven. Oh the crap storm that is going to fall upon the Earth will be horrific!
