Wether God is their Father or Satan, they are humans first and foremost.
Not half human, half angel, not alien from other planets.
I never mentioned alien from other planets.
If you believe the Nephilim were legitimate humans, being offspring of a human father and mother, then so be it.
Now it came to pass, when men began to multiply on the face of the earth, and daughters were born to them, that the sons of God saw the daughters of men, that they were beautiful; and they took wives for themselves of all whom they chose.
And the LORD said, “My Spirit shall not strive with man forever, for he is indeed flesh; yet his days shall be one hundred and twenty years.” There were giants on the earth in those days, and also afterward, when the sons of God came in to the daughters of men and they bore children to them. Those were the mighty men who were of old, men of renown.
Genesis 6:1-4
- There were giants on the earth in those days, and also afterward, when the sons of God came in to the daughters of men and they bore children to them.
I personally believe, the sons of God were angels, and did in fact survive the flood, and continued to produce Nephilim after the flood, in which the children of Israel had to drive them from the promised land.
