But most of them think the “son’s of Seth” hypothesis is the weakest of the bunch.

Based on what evidence?

Extra biblical writings?

[RoosterRedux]

Since the beginning of the written Hebrew language and surely before, when what is now the Hebrew Bible or Old Testament was passed down orally, the term "bene elohim" (Sons of God in the original Hebrew) meant one thing: angels.

Throughout the entire Old Testament, "bene elohim" means only one thing: angels.

The Sons of Seth hypothesis is nothing more than a weak modern literary contortion developed to deal with the uncomfortable story of fallen angels mating with human women.

BTW, the ancient Hebrew stories are mirrored in other cultures of the same era. Ancient Sumerian and Mesopotamian stories line up with the Hebrew Book of Genesis (albeit with different protagonists) as do stories from ancient China and India.

All this said, what you want to believe is your business.
