Genesis 6:1 sure is avoided by all the clergy I have queried. Most who use the Bible to declare ETs as demon seem to do so through misinterpretation.
“26 And God said, Let US make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth.
27 So God created man in HIS own image, in the image of God created he him; male and female created he them.
Is it US or HIS?
And when reading it metaphorically here is another perspective. Adam was the first “finished” product of this long genetic effort. So Eve had to be created from Adam. Eden was in the other dimension. These finished products were chosen to remain in that dimension to enjoy those powers and technology. The serpent was one of the other entity species in that dimension who shared the knowledge that our physical dimension existed. They were cast out from that dimension into our current physical dimension for collaborating with the serpent species.
So there are both good and bad entities and one is protecting us from the others, And from ourselves, and in turn also protecting their own interlaced dimension.
