Do you believe the seed of the nephilim survived the flood and became Canaanite kings? Finding it difficult to reconcile the genocide directed by the word of God.

“The Nephilim were on the earth in those days, and also afterward”
Keywords; “also afterward”.
If you continue reading in Genesis 6 after these verses you’ll see the context is the days of Noah and the flood.
As per Deut 32 and Ps 82 you’ll see other sons of God who were allotted the nations also rebelled at some stage.
The scriptures are clear that there were Nephilim giants after the flood, and this is why orders were at stages to kill all (man, woman, children and even animals) to eradicate the corrupted seed.
The 1 Enoch and the Book of Giants go into details around the depravity of these Nephilim of mixing seeds and creating hybrids even with animals.
This is the Orthodox position as well
Nothing but a 404

This episode of Blurry Creatures with Timothy Alberino 4 years old started me on the path towards seeking more from the Bible and the supernatural worldview of it and its authors, which IMO has been lost in the modern church.
There are so many amazing episodes, but this is the one that got me early on.
