Genesis 6:4-6

The Nephilim were on the earth in those days. That was when the sons of God went to the daughters of human beings. Children were born to them. The Nephilim were famous heroes who lived long ago. Nephilim were also on the earth later on. The LORD saw how bad the sins of everyone on earth had become. They only thought about evil things. The LORD was very sad that he had made human beings on the earth. His heart was filled with pain.
