No actually, the "sons of God" phrase used in The New Testament Books is about the Redemption of our body at Christ's second coming, and that future Resurrection state is like my Lord Jesus Christ said, "as the angels of God in heaven".
That totally disproves your false assumptions that the "sons of God" phrase is about the flesh.
This prove Angels in Gen 6

Gen 6:3 - - God's Spirit would not continue to strive with man in his fleshly sinful state, but no mention of His
Spirit striving with Angels?
Could it be that Angels are Spirit also?
Notice Veteran how the verb diyn means to contend, strive, decide, judge, and so forth.
Diyn:
to judge, contend, plead
a) (Qal)
1) to act as judge, minister judgment
2) to plead a cause
3) to execute judgment, requite, vindicate
4) to govern
5) to contend, strive
(Niphal) to be at strife, quarrel
God is (symbolically) pronouncing His intention of "gathering to Himself His spirit" as in Job 34:14, the life principle of creation. God removed the breath of lives from all living creatures (souls) bar eight souls (lives) and as we all know Angels cannot die and are not mortal – they are eternal, immortal as the Father bearing His image perfectly, they are the Spirit beings who behold the very eyes of the Father and cannot sin, fall, lie, have no lust of flesh because they do not live under the condemnation of sin which leads to death. If they could sin then they would also die, they don’t, therefore the wages of sin is death has not hold over them.
Does Rom 6:23 apply to angels?
Veteran cannot explain this because it’s a paradox for him! On one hand he knows if an Angel sins then the royal law of Rom 6:23 must also apply, else Veteran’s god is unjust! On the other hand he has all this mythology running though his head that he cannot see truth.
Now watch Veteran run away, far away from this question by stringing together a whole number of misquotations only to evade the reality of this conclusion.
Angels cannot sin!...you will need to find another way to event your supernatural beings...
But don’t use Holy Angels...they are His Mighty Ones how always do His commands.
