Some real history.

If you have been following us, you know the "Histories of Eden" is loosely based off of a true story. In Genesis 6, it says:

"And it happened that, when humankind began to multiply upon the face of the ground, daughters were born to them. Then the sons of God saw the daughters of humankind, that they were beautiful. And they took for themselves wives from all that they chose. And Yahweh said, "My spirit will not abide with humankind forever in that he is Also of flesh. And his days shall be 120 yrs." The Nephalim were upon the earth in those days, and afterward,  when the sons of God went into the daughters of humankind and bore children unto them. These were the mighty warriors from ancient times, men of renown.-(Lexham English Bible)

Some argue that the "sons of God" do not refer to angels, but the word that is used usually refers to  heavenly beings - not sons of earthly kings. Some might also quote where Jesus said that "the angels in heaven do not marry or are given in marriage..."Of course, the key phrase is "angels in heaven."

These angels abandoned their posts in heaven and came to live on the pre-diluvian earth. The apocryphal book of Enoch records about 200 or so of them. According to the Book of Enoch, the Watchers brought knowledge and technology to man and helped them to create advanced civilizations before the flood.
