You refuse to learn what you THINK you already know. The sons of God in the text are the B'nai elohim. The same are in the story of Job.
Job 1:6 Now there was a day when the sons of God(B'nai elohim) came to present themselves before the Lord, and Satan came also among them.
Adam was the only man that was called son of God. All of his offspring was sons of man. The Nephilim are the offspring of the union of sons of God, B'nai elohim, and daughters of the sons of men. These were the mighty men that you are referring to.They were the hybrid race of giants which are neither sons of God nor sons of men, but are abominations which God destroyed in the Flood of Noah. Angels have seed. God said so. God cursed the seed of satan.
Gen. 3:15 And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel.
I have studied this subject for years, in English, Hebrew, Aramaic---nope---Angels do not procreate. It is nbot biblical nor does it have any common sense at all. Again, the bible says all creatures have offspring after their own kind---0angels are not our kind, we are lower than they are. God calls those who follow Satan the children of Satan just as He calls those who follow Him His children. The passage itself calls them---men.
Gen 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.
This just says there were giants in those days, before and after the flood. No one knows how tall Adam and Eve were. They were not as we are, they lived for over 9oo years, what makes yo0u think they were as short as us? It's called genetics. They were tall and pockets of those tall genes have come down to us even today--it runs in families, also
These are not the offspring of angels---strange, what if there were short people then also? Were only the tall offspring of fallen angels but with short people it's just genetics? The very tall are not only because of acromegaly, there are thousands that are just very tall---and there are people with 6 finger or more today. Goliath and his family were not offspring of fallen angels, they were genetically giants---even the land there was a pocket that also grew large produce, like the cluster of grapes thsat required 2 people. Go to Alaska, they grew giant veggies there all the time. You can look all this stuff up in the internet.
The gathering in Job is a gathering of the representatives of other worlds---Satan came as the representatives of this planet for at the fall he acquired kingship of it and
the bible refers to him as the god of this world--
2Co_4:4 In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them.
What kind of God is it that would make billions of all male angels with the equipment to have sex and the desire for it, but noit make a way for them to use that equipment? God is not the God of dysfunction, or confusion! What is makes is perfect and the angels are above us. We can not have children with them.
It would be far more useful for you to spend yo0ur time with the study of His word instead of the study of the vain imaginings of men who have no idea of what the antediluvians were! You think they were a bunch of Neanderthals, sitting around the campfire grunting and chewing of raw bones?? Have you ever looked up what the savants are able to do, and they are partially retarded? The antediluvians were not retarded in any way. Those people had perfectly functioning brains, were giants(compared to us) and lived over 900 hundred years in which to perfect their abilities. These silly people who go on about these building that no human could have possibly built have no ideas what they are talking about! The pre-flood people were far more advanced even than us. Their knowledge was lost after the flood is all. They needed no help from fallen angels to do anything! God gave them perfect brains which they used for evil. The only thing fallen angels wanted to do was to kill us all off--they hate us! God obviously did not destroy the giants in the flood for they were around after the flood, such as Goliath.
The destruction of the people in the flood had nothi8ng to do with bloodlines, but everything to do with what God said He destroyed them for:
Gen 6:5 And GOD saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually.
Gen 6:6 And it repented the LORD that he had made man on the earth, and it grieved him at his heart.
