As an aid to your reevaluation of the above, I suggest you consider Who it was Who called Himself, "The Son of Man"...
Thanks for the input. There is one Son of God, Jesus Christ, as you know. This verse refers to sons, multiple. As I said I’ve previously assumed one interpretation but on more study the idea that fallen angels married or had children with humans doesn’t fit with the whole counsel of God. The idea that followers of God took up with pagan unbelievers is a warning God repeatedly gave to Israel and to Christians not to be unequally yoked with unbelievers. I guess any further questions should be private?
