Researcher and expert on Giants, Steve Quayle tells the story of a book written by Buffalo Bill Cody relating his lifelong encounters with American Indians. Cody recorded much of their lore and legends. Quayle explains the concept of greeting an Indian by raising your hand with palm extended and uttering, “How!” is a myth perpetuated by Hollyweird and promoted in cowboy and Indian TV shows and movies. In reality, Quayle states Buffalo Bill claimed that was actually a testimony that “we are not one of them,” meaning by virtue of displaying only 5 fingers rather than 6, they were not Nephalim. Cody also recorded legends of giant, hairy, humanoid beasts that could chase down buffalo and bull-doggy them much like a cowboy would today with a calf.
Re Western Giants:
Interesting. Found it!
“During the scouting expedition that followed, the party chanced upon an enormous bone, which the surgeon pronounced the femur of a human body. Will understood the Indian tongues well enough to be in part possession of their traditions, and he related the Sioux legend of the flood.
It was taught by the wise men of this tribe that the earth was originally peopled by giants, who were fully three times the size of modern men. They were so swift and powerful that they could run alongside a buffalo, take the animal under one arm, and tear off a leg, and eat it as they ran. So vainglorious were they because of their own size and strength that they denied the existence of a Creator. When it lighted, they proclaimed their superiority to the lightning; when it thundered, they laughed.
This displeased the Great Spirit, and to rebuke their arrogance he sent a great rain upon the earth. The valleys filled with water, and the giants retreated to the hills. The water crept up the hills, and the giants sought safety on the highest mountains. Still the rain continued, the waters rose, and the giants, having no other refuge, were drowned.
The Great Spirit profited by his former mistake. When the waters subsided, he made a new race of men, but he made them smaller and less strong.
This tradition has been handed down from Sioux father to Sioux son since earliest ages. It shows, at least, as the legends of all races do, that the story of the Deluge is history common to all the world.”
