There is much talk on the Internet about the Nephilim. Most seem to adhere to the idea that they were all physical giants because of the word gigantis which seemed to be transliterated as giants in the KJV. I know there are also mention of giants, probably real giants, in other passages of the Bible, but what do you think of the continuing statement in Genesis 6:4 where it says: …the same became mighty men which were of old, men of renown? Could this also mean that some were perhaps just mental giants? I have heard that the fallen angels or perhaps the Nephilim also taught mankind many things. Do you think that maybe all the Nephilim were not physical giants and some might account for these bursts of knowledge?
According to my research the Nephilim, in addition to being very large and strong, had enormous psychic abilities. They performed out of body experiences, levitation, mind control, time travel, mind reading and remote viewing. They had the power of pronouncing and removing curses and diseases, and had ways of knowing and predicting the future. Having aligned themselves with Satan, the source of their powers, they controlled and enslaved mankind and perverted God’s creation almost beyond redemption.
They were also extremely intelligent. They knew all about science, architecture, and engineering. Some believe they combined these skills with their powers of levitation to build the Great Pyramid and other great monuments around the pre-flood world.
I’ve also read that they sacrificed human beings all over the planet in temples and pyramids they built in Central and South America, the Far East, the British Isles, Egypt and other places. They drank our blood and slaughtered our babies, and were almost certainly tampering with both human and animal gene pools to pervert the creation and make our redemption impossible. They were the mighty men of renown, memorialized in every mythology, and the primary reason God had to destroy the world and all its inhabitants in the Great Flood.
