The book of enoch says nothing about hybid nephilim walking the earth today. The book specifically states that they are all DEAD. What remains of them are their spirits which shall bring destruction upon humanity until the consummation of the ages. The book is used by sorcerers and magicians to gain an understanding of the spiritual world. The 'people' who were once called sons of God are dead, their legacy is the things they brought into this world... IE: statism, government, sorcery, magic, idolatry, murder, war, etc... Those things are the spirits of the nephilim, they are the spirits of man birthed by our ego (aka the devil, the flesh, pan, prometheus, etc...) Demonology has more to do with modern psychology than anything else. Drop the superstition and fantasy.
