How is your's when reading these two verses which do not make sense if one thinks we are talking human/human
Genesis 6:1 "And it came to pass, when men began to multiply on the face of the earth, and daughters were born unto them,"
This verse tells us already that men and women were marrying, multiplying, etc and having daughters. Men can't multiply without women giving birth,etc. It doesn't matter who they are, these are human men and women multiplying, having offspring.
The thought continues,
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."
People can spin this in any fashion but the two verses do not make sense if we are merely talking human men and women in verse 2. First that's completely redundant. Secondly, it's not normal that giants were being born out normal offspring between human men and women. But if that's your "reality" than fine. I'm fine with mine as well.
Do you understand the difference between Adam's dead corruptible flesh, and God's permanent incorruptible physical body?
Adam's flesh is temporal fading away. The physical body of God is permanent that cannot decay nor fade away.
Do you have an issue that God's permanent body was created larger than Adam's dead flesh? You seem to have no problem that angels are larger than humans. It was never about them being human. It was about the sin that Adam's offspring carried with them, and the fact that Adam lost the physical body he was created with.
It was not the angels that corrupted Adam's dead corruptible flesh. It was already corrupted. Adam's daughters would have corrupted the angels, and turned them into disobedience creatures. The daughters of Adam corrupted the perfect sons of God.
You have it that perfect created angels corrupted Adam's flesh, the wrong direction of corruption. The sons of God did not corrupt Adam's flesh, it was Adam's flesh that corrupted the sons of God.
The angels were not involved in this corruption. If there were giants before Adam even disobeyed God in the Garden of old, already ancient, then Adam was not the only son of God. There were many generations of sons of God hundreds of years, a thousand to be more exact, before Adam disobeyed and brought sin into the world, and hundreds of years after Adam and Eve were cast out of the Garden. What happened in Genesis 6 could have been over 30 generations after the 6th day creation of humanity. Are you saying the angels were around procreating with humans for over 24 generations, and then suddenly those last few generations became corrupted and wicked? Once again it was Adam the only son of God who brought sin into the world, and death by sin. The sons of God those created on the 6th day became corrupted from the daughters of Adam. The offspring allowed giants into Adam's dead corruptible flesh. But the offspring were also sons of God in Adam's image, and no longer in God's image.
Now human flesh would be strange to angels. How much more so the sons of God, humans created in the image of God saw the strange flesh that was dead and corrupted by Adam's disobedience and was no longer God's image but the image of sin and disobedience that enticed the perfect without defect sons of God. Sin may be pleasurable for a season, but the end is death, and all that remained on earth was corruption that had to be destroyed.
