The Nephilim are mysterious beings mentioned in the Bible, most notably in Genesis 6:1–4. They’re described as the offspring of the “sons of God” and human women, often portrayed as giants or mighty warriors who lived in ancient times. Their presence is tied to growing corruption on Earth and is one of the reasons given for the Great Flood in the biblical narrative. Across religious texts and later traditions, the Nephilim have been interpreted variously as fallen angels’ children, powerful humans, or legendary heroes, which keeps them a big topic of debate and myth-making.
