Genesis 6:2: "the sons of God saw that the daughters of humans were beautiful, and they married any of them they chose." There are some interpretations that say that "the sons of God" should be interpreted "angels." Revelations in the Bible tells us that the tail of the dragon swept a third of the stars out of the sky and flung them to the earth. The "stars" are often interpreted as "angels." Wake up and see that the stupid popular understanding of prehistory is mixing up all kinds of stuff that would be clear if we only recognized that the Bible talked about it clearly, long, long ago.
