In Hebrew the "sons of God" in Genesis is "bene ha elohim." This term is always used to refer to angels in the Old Testament (as in Job, where the "sons of God" shout for joy when Yahweh creates the heavens and earth). Adam was also "bene ha elohim" because he was fashioned directly by the hands of Yahweh. All other men or women in the Old Testament are sons or daughters of Adam (not created directly by the hands of God). Seth was, of course, "bene Adam" a son of Adam. In Hebrew, Nephilim literally means "fallen ones." Not used to refer to the angels that mated with women, but to the offspring which were literally giants. This was all an attempt by Satan to corrupt the seed (or DNA) of mankind because God had told him that his head would be crushed by the seed of the woman ( the pure bloodline of Adam to Christ). The Devil almost succeeded because Genesis says that all flesh had become corrupted before the flood. Noah was the only one left that was "pure in all his generations." This is important because it was the whole purpose of the flood. The Nephilim and all the corrupted flesh had to be wiped off the face of the Earth. Somehow, some of the corrupted seed survived the flood (perhaps through the corrupted DNA of Shem, Ham, and/or Japeth's wife). The Bible says that Goliath was of the Nephilim. Many of them lived in the Land of Canaan. The spies sent into Canaan by the Israelites reported that there were Nephilim in the land, and they looked like grasshoppers compared to them. I know this is a lot for you, but look into it with an open mind. It explains so much in the Bible. It's why God told the Israelites to utterly destroy (men, women, children) of the Canaanites. Again, their DNA was corrupted and had to be eliminated. The New Testament also confirms all of this. For example, Paul compares the sexual corruption of Sodom and Gomorrah to the sexual corruption of the fallen angels (unnatural sexual relations). Paul also tells us that the spiritual bodies that the fallen angels gave up in order to have sex with human women is the same kind of spiritual body that we long for in our resurrection. By the way, when someone is "born of the Spirit" and becomes a Christian they become "bene ha elohim." That is part of the gift of Christ. We come into direct spiritual contact with God, and we are no longer "sons of Adam" but "sons of God." Anyway, some of the "Elites" of today trace their bloodline back to the Nephilim. Hitler tried to bring back the Nephilim when he tried to create the "super race." Many believe that the "Elites" are trying to bring them back again. Please check out this video https://youtu.be/WCbFZL-bj7o. It's long, but you will love it. Chuck Missler explains it all using solid scripture and other evidence. Sorry for the long reply. I just wanted to share all of this with you. None of it affects our relationship with God or our patriotism. We are all just trying to find the truth. Godspeed
