There are three theories, about what the “sons of God” are, that I want to consider: (1) they are angels, presumably fallen angels; (2) they are the faithful from the line of Seth, those who called on the name of the Lord or walked with the Lord; or (3) they are all men. Now, there is little evidence internal to the Bible that the phrase here meant demons or demonic spirits (fallen angels), whether embodied themselves or inhabiting the bodies of wicked men—though the phrase “sons of God” does sometimes mean angels. The famous but certainly pseudepigraphal (i.e., falsely attributed) Book of Enoch suggests it; but it was written in the 100s AD, not at all by Enoch, and represents a highly conjectural theory, not scripture. Observe, in support of the line of Seth theory, that the previous two chapters did explain and contrasted in detail the two different lines—and that these lines come at the end of the toledoth about the line of Seth. This then raises the question: did the lines intermarry? And if so, what was the result? We are told what the result was, and so we should perhaps settle the question in the context of the remarks about nephilim in Gen 6:4. As to the third theory, this is also intiguing, because, as Sailhamer has argued, the “sons of God” might well be all men, because Adam was created by God. In that case, the “daughters of men” would be women because Eve was made of Adam’s rib. Then the comments in Gen 6:1-2 regard the totality of the “multiplying” generations of man, of all men, who are shortly to be done away with for their wickedness.
