In the Bible - the term "sons of God" as we see it in John 1:12 and in Deut 32:8 and Matt 5:9
Deut 32:8 When the Most High gave to the nations their inheritance, when he divided mankind, he fixed the borders of the peoples according to the number of the
sons of God.
Matt 5:9 Blessed
are the peacemakers, For they shall be
called sons of God.
John 1: 12 But as many as received him, to them gave he power to
become the sons of God, even to them that believe on his name:
So then the contrast is between those who serve God and those who serve him not in Genesis 6 - the very real and serious problem in both OT and NT of being joined to unbelievers. Not the less-than-serious problem of forming families with aliens from outer space.
The term is never used for someone at war with God ... whether man or angel.
That the sons of God are contextually made distinct from the daughters of men, and that their actions are tied to the wickedness of man ought to be enough to make that apparent.
Certainly it does make it apparent that this is a very real problem for us - and we should preach against doing that very thing - as is done all the time. But it is not about aliens,,, it is about the very common problem of being joined to unbelievers.
BTW - if the book of Enoch were even legit - then it would have had to have been written by Enoch - only lost to us to today in its Hebrew or ??? form... and if that were the case it must have already existed at the time of Moses - and yet it was not known to them, not placed in the ark.. not even mentioned when Moses goes through the history of the world at the time of Enoch and not disclosed to Moses by God for over 40 years of direct contact. In other words if the Bible is true - the book of Enoch was not written by Enoch.
That their actions are associated with the wickedness of man ought to make that apparent.
All through the OT the act of joining believers to unbelievers is linked to the apostasy of God's people. You see it in almost all the wicked kings of Israel.
"When" does not mean "before"
"and also afterward" means that what happens earlier is "before".
4 "The
Nephilim were on the earth in those days
and also afterward when the sons of God came in to the daughters of men"
It cannot be morphed into "The
Nephilim were on the earth in those days but ONLY AFTER the sons of God came in to the daughters of men because that is how the Nephilim came into being"
In real life today we know that if group A has a certain trait and then one family from group A goes to a new location and forms another group B out of their own ... and group B ALSO has that same trait -- then the people that went from A to B had the trait. Noah was Nephilim as was Adam.
