The mighty nephilim giants of Genesis are gone but Revelation describes their reappearance to play a major role in the end times. Despite this, few christians know anything about the nephilim. Many people view the Greek gods, titans, half-man half-animal and half-god half-man as myths but as a believer if you study your bible and other apocrypha books you would be forced to believe the Greek gods trully exists or existed. Understanding the nephilims will give a clearer understanding of the demonic locusts of revelation, antichrist/beast and false prophet and the abyss. It also may explain why there are persistent reports of UFOs and alien life in the world today.

WHO ARE THE NEPHILIM?
The nephilim are one of the more mysterious and disturbing topics of the Bible, the word nephilim only appears twice in the Bible. Gen 6:1-4, Num13:32-33.
Nephilim literally means fallen ones. Early interpreters believed them them to be giants. The nephilims(giants) came as a result of angels mating with humans.

By the way nephilims are not humans but humanoids so they are not entitled to salvation. This partly answers to what happens to a nephilim when it dies. Gen 6 shows how God destroyed the nephilims through the flood and saving only Noahs family. As for the wicked angels who parented them the Bible also describe their fate jude 1:6-8, 2pet2:4. The Bible shows in Gen 6:4 that there were still giants(nephilims) ater the flood. e.g Goliath and his four brothers(2sam 21:16-22 and 1chr 20:4-.

They will be back

in fact, there are several races of giants listed in the OT after the flood :
1) Rephaim(Gen 14:5).
2) Anakim(Num 13:33).
3) Emim(Gen 14:5).
4) Zuzim(Gen 14:5).
5) Zamzummims(Deut2:20).
6) Zophims(Num 23:14)

So where did these giants come from? The Bible does not directly tell us. One possibility is that the fallen angels repeated their sin to create more nephilim after the flood. This is possible because not all did this sin. Note in the passages of Jude and Peter above how the Bible says "those angels who sinned and those who kept not their first estate" this implies that not all the one third of the fallen angels who followed satan had sex with women(The Book of Enoch puts the number at only 200).

WHERE DO THE DEMONS COME FROM?
This question is not answered anywhere in the Bible but the Book of Enoch does, even though Enoch is not scripture, but NT itself quotes Enoch(Jude1:14). What Enoch indicates is that the demons are the spirits of the nephilim released upon their death.
