Much speculation has been perpetuated over the years on this subject. The most popular answer, and subsequently the most represented in film, mythology, and stories, has been that the sons of God were angels that began to mate with and take wives of the female descendants of Adam. This idea has led to stories being written about mythological creatures resulting from these unions called Nephilim which are supposed to be some kind of half human-half angel hybrid. The second view is that the “sons of God” refer to the bloodline of Seth while the “daughters of man” reference the bloodline of Cain. This view is more consistent with scripture. Several pieces of evidence combine to support this convincing claim.
