The Nephilim (Hebrew: נפלים, Nefilīm) were a race that came to dominate the antediluvian (pre-flood) world, and are referred to in the Bible as the heroes of old, men of renown. They were reportedly the children born to the "Sons of God" by the "daughters of men", and are described as giants. It is also most important to note that they are mentioned almost simultaneous to God's statement that He would destroy the earth by flood, and it seems from this association that their effect upon mankind was one of the primary justifications that brought the destruction.
