Sorry, I missed this part earlier. I get lost in your posts sometimes, start following links that you provide, and then never get back to finish reading the whole post. (Yes, I am easily distracted...lol...).
I find this intriguing. I had not heard the idea before that the genocide of the Canaanites may have been related to the purging of the Nephilim. I will look further into this...
Peace...
The New Testament confirms the Flood and Sodom and Gomorrah.
2 Peter: 2. 4. For if God spared not the angels that sinned, but cast them down to hell, and delivered them into chains of darkness, to be reserved unto judgment; 5. And spared not the old world, but saved Noah the eighth person, a preacher of righteousness, bringing in the flood upon the world of the ungodly; 6. And turning the cities of Sodom and Gomorrha into ashes condemned them with an overthrow, making them an ensample unto those that after should live ungodly;
Any supernatural hybrid mutants would have been destroyed.
Genesis: 7. 21. And all flesh died that moved upon the earth, both of fowl, and of cattle, and of beast, and of every creeping thing that creepeth upon the earth, and every man: 22. All in whose nostrils was the breath of life, of all that was in the dry land, died. 23. And every living substance was destroyed which was upon the face of the ground, both man, and cattle, and the creeping things, and the fowl of the heaven; and they were destroyed from the earth: and Noah only remained alive, and they that were with him in the ark.
Here are the generation's of post flood people who were cursed by Noah.
This includes Canaanites and Sodom and Gomorrah.
Genesis: 10. 6. And the sons of Ham; Cush, and Mizraim, and Phut, and Canaan. 7. And the sons of Cush; Seba, and Havilah, and Sabtah, and Raamah, and Sabtecha: and the sons of Raamah; Sheba, and Dedan. 8. And Cush begat Nimrod: he began to be a mighty one in the earth. 9. He was a mighty hunter before the LORD: wherefore it is said, Even as Nimrod the mighty hunter before the LORD. 10. And the beginning of his kingdom was Babel, and Erech, and Accad, and Calneh, in the land of Shinar. 11. Out of that land went forth Asshur, and builded Nineveh, and the city Rehoboth, and Calah, 12. And Resen between Nineveh and Calah: the same is a great city. 13. And Mizraim begat Ludim, and Anamim, and Lehabim, and Naphtuhim, 14. And Pathrusim, and Casluhim, (out of whom came Philistim,) and Caphtorim. 15. And Canaan begat Sidon his firstborn, and Heth, 16. And the Jebusite, and the Amorite, and the Girgasite, 17. And the Hivite, and the Arkite, and the Sinite, 18. And the Arvadite, and the Zemarite, and the Hamathite: and afterward were the families of the Canaanites spread abroad. 19. And the border of the Canaanites was from Sidon, as thou comest to Gerar, unto Gaza; as thou goest, unto Sodom, and Gomorrah, and Admah, and Zeboim, even unto Lasha. 20. These are the sons of Ham, after their families, after their tongues, in their countries, and in their nations.
