As in The Days Of Noah

“But as the days of Noe were, so shall also the coming of the Son of man be.” Matthew 24:37
In the end of time, the bible says that it will be like it was “in the days of Noah”. So if we could figure out what was happening in Noah’s day, we might have a much better understanding of what Jesus meant when He said that.
In Genesis chapter 6, we read exactly why God sent the flood to destroy the earth and all the people living on it with the exception of Noah and his family. Fallen angels had  ”left their first estate” of Heaven to come down to human women, and impregnate them. The resulting offspring became Nephilim, the “giants” that are mentioned all through the bible. The bible says that these giants were wicked creatures that could not be redeemed, so God destroyed them.
