Survival of the Nephilim After the Flood

Somehow the Nephilim survived after the flood, but how did they do it?

The Bible and extra-biblical texts such as the Book of Enoch don't tell us exactly how this happened,

but there's little bits of information we can pull from and derive some theories.

One Jewish text says King Og, a Nephilim giant, held onto the side of Noah's ark.

A very plausible explanation is that Nephilim genetics lived on from one of the people who

was on Noah's ark. But I believe the most plausible theory is connected to what happened the

first time Nephilim appeared on the Earth, and that's when the fallen sons

of God came to Earth the first time, took wives for themselves, and created these Nephilim offspring.
