You are right about what I think about it. So, I have a question? Does any of that speculation and mental wanderings serve one single useful, enlightening, edifying, theological purpose? IMO it is not the stuff of mature Christians.
Yes, mulling these things over
does serve a useful purpose. It has to do with the "mark of the beast" found in Revelation 13.
We know that God did not design for the different species to intermingle with each other. Everything of creation was to produce "after its kind". For the beasts, birds, fish, etc., this reproduction was to replace themselves when animal death naturally occurred. Fallen humanity likewise was designed to reproduce originally, but became subjected to death by their own sinfulness, and thus needed even more to have that level of conception increased.
The angelic, celestial sons of God were NOT to reproduce, since God originally designed for them to be deathless - needing no replacements. They are all presented as male in scripture - no female among them. But when some rebelled against their "first estate", and left their heavenly habitation to marry human women and produce offspring, this broke God's rule for their angelic species, and resulted in hybrid angelic / human sons who became giants, and "men of renown" in the days of Genesis 6.
Even in ancient pagan religions, there are depictions of hybrid demi-gods that were a mix of human and divine.
The image of one of these demi-gods (Melqart /Herekles /Hercules) was stamped on the face of the Tyrian shekel that the Jewish high priesthood had required for use in the temple. No one could either buy or sell sacrificial items for worship in the Jerusalem temple without using that profane Tyrian shekel with its forbidden, abominable images and inscriptions.
This Tyrian shekel coin with that demi-god image on the front was what Revelation 13 called "the mark of the Beast" which gave homage to the Roman phase of the Rev. 13 Sea Beast. Everyone high or low was required to use this Tyrian shekel coin when they came to the temple for worship. And everyone coming to the temple from any other nation had to exchange their own foreign currency for the priesthood-approved Tyrian shekel which the Jews had begun to mint for themselves after the priesthood in 19 BC had asked Rome's permission to do so. This transaction fee was collected by the money-changers: the ones which so angered Christ for turning His Father's house into a "den of thieves" by this profane requirement.
Long ago in Deuteronomy 7:25-26, God had made strict commands
against using the silver or gold of the graven images of Canaan's gods. "
The graven images of their gods shall ye burn with fire: thou shalt not desire the silver or gold that is one them, nor take it unto thee, lest thou be snared therein:
for it is an abomination to the Lord thy God. Neither shalt thou bring an abomination into thine house, lest thou be a cursed thing like it: but thou shalt utterly detest it, and thou shalt utterly abhor it; for it is a cursed thing." Achan who broke this rule found out that God was absolutely serious about this command when he and all of his were stoned to death and burned for this offense.
In spite of this very clear command in Deuteronomy 7 NOT to take the gold and silver images of Canaan's gods unto themselves, those high priests in Christ's days had not only been doing this, but
they were requiring this for everyone coming to the temple, and in addition were making everyone pay a fee for participating in that forbidden practice which went against God's laws.
Once we understand that God in Genesis 6 had to flood the entire world to kill off the hybrid angelic / human sons which had grown to be giants in the earth, we can understand just why that high priesthood-required Tyrian shekel image of a demi-god was so utterly offensive to God, and why that Tyrian shekel deserved to be excoriated as "the mark of the Beast".
