Hey, I know people here. My grandfather told me, after the creation modern Israel, the churches were full and preachers were preaching on the sidewalks because everyone realized the world was not going to last. Prophecy had been fulfilled.
Also, if the children were part divine beings they would not have sin in their hearts so there would have been no need to destroy the world and kill the innocent along with the guilty.
I believe the sons of God were the old generation like Adam and Cain. They looked at the younger daughters of men and took them. The old ones still had the original perfect genes so having children with the youngest generation must have produced powerful offspring. This makes more sense to me...
