It’s why I get so frustrated by the people who actually believe these things are benevolent aliens from some other planet, when they’re anything but. They are giving into the “great deception” Jesus warned about in Revelation. But yeah it sounds like we’ve looked at a lot of the same research. I’ve heard a pastor say that Nimrod was technically the first “mason” and yeah, was a nephalim. Whether the antichrist is Nimrod 2.0 or not, I think it’s a safe bet that he will definitely be a hybrid nephalim. There’s another guy who deep dives on this stuff named Gary Wayne. That’s some interesting listening if you get a chance. One thing he pointed out was that these “royal bloodlines” all over the earth are (or they actually believe that they are) descended from nephalim tribes. It all definitely fits within the “seed of satan” passage early in Genesis and other such passages throughout the Bible.
