In view of the likelihood of Nephilim infecting our world again, I think perhaps the Antichrist and the False Prophet could be Nephilim. My reason is simple. In Rev. 19:20 neither of them die, but both are thrown directly into the Lake of Fire without an appearance at a Judgment. If they were human, they would be at the Great White Throne Judgment. Even the demons in Jude 6 are awaiting judgment. Possibly Nephilim, being half human and half demon won’t judged. How do you see this?
Just as there is Biblical precedent for men being taken into Heaven without dying first (Enoch and Elijah) There is also Biblical precedent for men being sent into Hades without dying first (Korah, Dathan, and Abiram, Numbers 16:31-33).
Therefore, I don’t think the fact that the anti-Christ and false prophet will be thrown live into the lake of fire proves conclusively that they’re nephilim. I know there are many who believe there will be some kind of alien involvement in the end times, and I’ve speculated about it a time or two myself. But while this is an area of interest to many, the Bible is by no means clear on the topic, and where the Bible is not clear men are prone to speculation.
One thing I am convinced of is that we can’t use Matt. 24:37 “as it was in the days of Noah” to support any end times nephilim claims. Jesus used the phrase to explain that just as the people of Noah’s day had no idea their world was about to end, so it will be with a majority of people on Earth at the end of the Age. They’ll know they are going through terrible times but they’ll believe things will eventually get better just like they always have. They won’t realize what’s really happening until they see the Lord coming on the clouds, and by then it will be too late. That’s why they will mourn at the sight (Matt. 24:30).
