[Mark17]

Possibly, but as I understand it, the fallen angels did the Genesis 6 thing over again, some time AFTER the Flood, when the population had become somewhat restored. That would explain David’s run-in with Goliath centuries after Noah’s Flood. The last giant named in the Bible was Og, king of Bashan. He was killed by Jewish soldiers, if memory serves.
