The sons of God in Genesis 6 were men, not angels.
Genesis 6:2 That the sons of God saw the daughters of men that they were fair; and they took them wives of all which they chose. Matthew 22:30 For in the resurrection they neither marry, nor are given in marriage, but are as the angels of God in heaven.
Angels don't take wives. The sons of God were men, not angels.
Genesis 6:4 There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became mighty men which were of old, men of renown.
Giants are men (Numbers 13:32,33). Mighty men are men. Men of renown are men. The sons of God were men. Men beget men; that's the way it works.
John 3:6 That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.
Like begets like. Men are flesh. Angels are spirits (Hebrews 1:14). The sons of God were flesh. Flesh begets flesh.
Romans 5:12-18 Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men ... as by the offence of one judgment came upon all men to condemnation ...
The giants, mighty men, and men of renown were born sinners, just like the rest of us, because they were descendants of Adam, not angels.
Jude 1:6 And the angels which kept not their first estate, but left their own habitation, he hath reserved in everlasting chains
under darkness unto the judgment of the great day.
There's no mention of angels marrying women here. Have you ever moved from one estate to a new habitation? Did that cause your new house to get pregnant? The sons of God were men, not angels.
2 Peter 2:4 For if God spared not the angels that sinned, but cast them down to hell, and delivered them into chains of darkness, to be reserved unto judgment;
The angels "sinned". That's a broad term. There's no mention of the angels marrying & impregnating women in this passage. The sons of God in Genesis 6 were men, not angels.
Psalm 8:4,5 What is man, that thou art mindful of him? and the son of man, that thou visitest him? For thou hast made him a little lower than the angels ...
Men and angels are distinctly different creatures from each other: God made them that way. The sons of God were men and they begot men.
1 Timothy 2:5 For there is one God, and one mediator between God and ... angel/man hybrids? I don't think so. Some extra-biblical "Enoch" might have thought so, but I don't. Jesus was the one and only mediator between God and the mighty
men and the
men of renown.
Jude 1:14 And Enoch also, the seventh from Adam, prophesied of these, saying, Behold, the Lord cometh with ten thousands of his saints,
15 To execute judgment upon all, and to convince all that are ungodly among them of all their ungodly deeds which they have ungodly committed, and of all their hard speeches which ungodly sinners have spoken against him.
Who did the biblical Enoch prophesy of?
Verse 4 ... certain men crept in unawares, who were before of old ordained to this condemnation, ungodly men ...
Ungodly sinners who are men - not some mythical offspring of angels & women.
Hebrews 2:9 But we see Jesus, who was made a little lower than the angels for the suffering of death, crowned with glory and
honour; that he by the grace of God should taste death for every man.
Jesus tasted death for every mighty man and every man of renown. Their fleshly daddy's name was Adam, not Lucifer.
