If the "Bene HaElohim" were fallen angels, who were the Nephilim? Discuss their role in Biblical history, Greek mythology, and the end times BIB 522 - 02-4

Man has long tried to explain these Nephilim/ hybrids as the off-springs of the gods of old seducing the women of earth. I took two years of Latin in high school and really enjoyed the myths of the gods and goddesses of the Romans. The Greeks had very similar myths of beings who were half men and half god. I found it to be interesting fiction or so I thought. Rather than legends of gods impregnating earth women it was the fallen angels who followed Satan.
 
Legends of the offspring’s of these unholy unions are told throughout the planet. The Nephilim had corrupted the earth with their hybrid off-spring. So the Lord said, “I will destroy man whom I have created from the face of the earth, both man and beast, creeping thing and birds of the air, for I am sorry that I have made them” (Gen. 6:5–7). Eight people survived the flood. We are told in Genesis 6:4 “The Nephilim were on the earth in those days—and also afterward—when the sons of God went to the daughters of the human beings and had children by them. They were the heroes of old, men of renown.” So the fallen angels were still spreading their progeny even after the flood wiped out all but eight people on the earth.

References are made to the Rephaites in Genesis 14 and in Numbers 13:33, “We saw the Nephilim there (the descendants of Anak come from the Nephilim). We seemed like grasshoppers in our own eyes, and we looked the same to them.” There are additional references in the Old Testament, enough to prove that they were still around after the flood.
In my opinion there are Nephilim today that are often referred to as ETs. Years ago I thought that ETs and abductions were a bleed through from another dimension; that this occurred when people indulged in occult practices thus opening themselves to ETs and inviting dabduction. There are many rather consistence stories of abductions and being probed, the fallen ones experimenting with human DNA?

After the Harpazo the Antichrist and his false prophet will invent many scenarios to explain away the disappearance of millions of people. One likely explanation will be that those raptured were holding the rest of the world back from evolving to a higher dimension so they were taken out by some unnamed and imaginary spiritual force. Today many are very involved in the occult and ETs (Nephilim). I would expect that they would be receptive to this explanation.
