That is why God brought the Flood to wipe out all vestiges of these hybrid Nephilim. Noah and his sons and their wives had preserved their pedigree and kept themselves pure in spite of the prevailing corruption brought about by the fallen angels (Oxford Companion Bible). In other words, Noah's bloodline had remained free of genetic contamination (Genesis 6:9). Noah and his family kept the human DNA pure and preserve the coming bloodline of Jesus, while the fallen angels who had perpetrated these blasphemies and attempted to corrupt the human bloodline of Jesus were kept in eternal bondage and chains in the pits of darkness.

The Nephilim appeared again in Numbers 13:33 and that is why God told Joshua to kill all the Canaanites-men, women and children. He again wanted to keep the bloodline, the DNA, pure. Thus fallen angels must have continued for a time to breed with human females.

While I do not know if there are any Nephilim present on the earth today, I believe that there are fallen angels roaming about to continue to deceive us humans.

The non canonical book of Enoch, while not a part of the Bible, is quoted verbatim in Jude 14-15 concerning the return of the Lord to execute judgment upon all. The Book of Enoch speaks of fallen angels as Watchers (as does Daniel 4:17) and says that the worst was Azazel. Azazel is the name of the fallen angel in both of my novels, The Great Harpazo Deception and Invasion: Israel.

Later and most importantly, in the three days between His crucifixion and His physical resurrection from the dead, after Christ had died for sins once and for all, for the just and the unjust, in order that He might bring us to God, having been put to death in the flesh, but made alive in the spirit, Christ also went and made a proclamation to these spirits (fallen angels) now in prison who once were disobedient in the days of Noah. He proclaimed His triumph over them and over sin, death, hell, and Satan (1Peter 3:18-20). When He had disarmed the rulers (fallen angels), He made a public display of them having triumphed over them (Colossians 2:15).

This is significant because Christ told His followers that just as it happened in the days of Noah, so shall it be also when the Son of Man is revealed (returns) (Luke 17:26, 30). Today in our world, we have goings on much like there was then including a great deal of sin and debauchery and possibly chasing after strange flesh by fallen angels (extraterrestrials). Look at all the immorality like pedophilia and child abductions as well as all of the UFO sightings, alien abductions and the cases of alien human hybrid experiments, and you will see a return to the days of Noah when the Sons of God (fallen angel extraterrestrials) mated with the daughters of men. You will know that the Lord is about to reappear very soon and take His own to be with Him in the clouds while all hell breaks loose here on earth. The sudden disappearance of millions will be explained as abduction by UFOs. We have been conditioned, programmed if you will, to believe such lies by the great Deceiver himself, Satan and his minions of fallen angels (extraterrestrials).
