I disagree that sons of God were angels. I think they were simply followers of God and sons of men were men of this world, non-followers like secularists or atheists.

Has to be! That's how those Giants (Nephilim) were made. Two humans of different religious or political differences got together and...that sexual union creates 8-10' tall (human?) half-breeds with six fingers and six toes. Not long after that God decides to flood the world (there were reasons).

It’s known in biology that the more healthier the human being, the taller and stronger they are. My reading of Scripture is that everything in a pristine Antediluvian world was simply bigger. The fossil record testifies to that.

I don’t read the description in Genesis that they were giants because of genetic manipulation, just that they were giants as part of their creation.
