Must be one of those peaceful agrarian communities that the conquistadors brutalized. /s
They attacked the locals up until around the mid 1800's when there was concerted efforts to wipe them out by the Texans. They were considered extinct about 1850. They kept attacking Texans settlers until and all out war was approved to get rid of them. They were never considered "noble warriors" as some tried to make other tribes of the plains. They murdered, raped and ate settlers until they were finally destroyed.
I teach Sunday school and I read about the Nephilim having red hair, 6 fingers and toes and were over 9 ft tall.
Num 13:32 And they gave the children of Israel a bad report of the land which they had spied out, saying, "The land through which we have gone as spies is a land that devours its inhabitants, and all the people whom we saw in it are men of great stature.
Num 13:33 There we saw the giants (the descendants of Anak came from the giants); and we were like grasshoppers in our own sight, and so we were in their sight."
We've thrown our children in the fires of Baal and Moloch since Genesis 6:1. The Commands given by God to Israel many times included rules to follow because of what the Nephilim taught the people. Don't drink blood for one. Make sure you kill your prey before you eat it. American Indians had legends about giants that chased down buffalo running away and they would tear off a leg and eat it raw. Nephilim taught earth dwellers sorcery, witchcraft, spells, and necromancy. Tattoo's were also common. Many of the curses read about in Deut. go back to what the Nephilim introduced on earth. That is why Noah and the Flood is introduced immediately after Genesis 6:1. This evil DNA has survived all the way to today and we call them Democrats. The seed war started back in Genesis 3 will continue until Jesus comes back to take care of Satan's seed called the Antichrist. Being able to murder children and commit sexual abominations is just a few signs of this corrupt DNA being passed through history.
