[21]And at that time came Joshua, and cut off the Anakims from the mountains, from Hebron, from Debir, from Anab, and from all the mountains of Judah, and from all the mountains of Israel: Joshua destroyed them utterly with their cities.
[22]There was none of the Anakims left in the land of the children of Israel: only in Gaza, in Gath, and in Ashdod, there remained.

[12]The Horims also dwelt in Seir beforetime; but the children of Esau succeeded them, when they had destroyed them from before them, and dwelt in their stead; as Israel did unto the land of his possession, which the LORD gave unto them.
There may be more ...but just these are evidence enough of nephilim after the flood. It would be good to search the Word to see how this occurred again after the flood. I believe the scripture (Genesis 6:4) explains it.
Jesus' words that the days leading up to His coming would be "as the days of Noah were" tells me that we are now in those days, since I and many other survivors of SRA/MK have seen the nephilim in modern times.
