What I said earlier is this:
By this I mean that to unravel this pericope we have primarily to understand what the term “sons of God” means. But when this is done then the “Nephilim” become also highly relevant because of the parenthetical remark “and also afterward” in Genesis 6:4: This remark implies that also after the Flood there were “sons of Gods”, that is, humans created in the image of God as Adam was created.
Agreed.
Nonetheless I am showing that in the light of evolution, the Old Testament (Genesis 5, Ps 29:1; 89:7; Job 1:6, 2:1,38:7) and the New Testament (Luke 3:38) the correct interpretation is that referred to above (human beings created in the image of God the same way Adam was created).
Genesis 1-11 is a good demonstration of 1 Kings 19:11-13: God often conveys his messages in “gentle whispers”, and we risk missing them if we believe they have to be accompanied by storms, earthquakes and fires (see Silence and Evolution by @jstump). And the amazing thing is that some of His messages in Scripture we can decipher only today thank interpretation keys we get through science: Genesis 6:2-4 is paramount. But in my view another example is Melchizedek as a non-adamic human person (this may also be of interest for @Swamidass, @Socratic.Fanatic @Jon_Garvey @Christy).
Cain was taught by God tat killing Abel would be wrong and a big sin (Genesis 4:7). However after Cain sinned God curses him with the words: “Your brother’s blood cries out to me from the ground” (Genesis 4:11), and not with the words: “from each human being, I will demand an accounting for the life of another human being” (Genesis 9:5).
In this sense Genesis 9:3-17 proclaims that the creation of humanity (creation of humans in the way Adam was created) was achieved.
