Genesis 6, according to the ancient writings of the Jewish Rabbis, the Fallen angels took human form and took wives of the daughters of men and the women had children of a mixed breed called the Nephilim. NOT what God had intended and according to Peter and Jude, the ones that did this are locked away awaiting judgement. The flood was to wipe them out and all of mankind except for Noah and his family. Noah, his sons and his wife were perfect in their generations meaning their bloodline was not corrupted. We are not told that this happened after the flood but the problem could have come through the bloodline of Ham's wife. The Nephilim were found in the land that Ham settled called Canaan. The angels that sinned may have drank human blood in order to have sex with women. The LIFE is in the blood. It was said the Nephilim ate human flesh and drank human blood---something the elite are known to do. The Nephilim had six fingers and six toes on their hands and feet. I wonder how many of them have this little detail?
