Yet again, this book. It is very well documented http://www.amazon.com/Ancient-Giants-Who-Ruled-America-ebook/dp/B00HDGKYS2/ref=sr_1_1?ie=UTF8&qid=1397312622&sr=8-1&keywords=giants+america
I fail to see what this has to do with von Daniken. I do not ascribe to any connection between Bigfoot and UFO's or Ancient Aliens. You may feel free to associate the topics, but I have never seen anything that would compel me to do so.
In my opinion, the use of the word "giant" to describe remains is problematic because it is both non-specific and has taken on a sensationalist connotation. Actual size should be used instead.
Logic:
1. Three mummified Si-Teh-Cah skeletons from a Cave near Walker Lake, Nevada were on display in Virginia City, Nevada for decades.
2. I personally viewed them multiple times.
3. Other mummified skeletons of the same people were found in Lovelock Cave, Nevada.
4. It is highly unlikely that this tall race of Native Americans was confined to a few dozen individuals living in two caves in Nevada.
5. One would expect to find such remains in other areas of America.
6. Large remains of similar description have been reported to be found throughout America.
7. The Smithsonian has been connected to several of these finds.
8. Thomas Powell, the head of the Smithsonian's Bureau of Ethnology is on record setting a policy "On Limitations to the Use of Some Anthropologic Data". This is the actual title he gave it and is in direct contradiction to the stated objective of the Smithsonian to broaden the diffusion of knowledge among men.
9. Thomas Powell was concerned that Native American anthropological finds would be used "unwisely", in his view, to connect Native American culture to "...so-called races of antiquity in other portions of the world". Powell's words again.
10. Powell was specifically concerned about anything that might link Native Americans to popular theological origins, which might engender positive public perception. Evidence of "giants in the earth" in America, qualified, and worse, the commonly accepted theological origin of such giants was also problematic to him.
11. Sensational title aside, the book referenced above documents the collection of such remains by the Smithsonian.
12. There is no accounting regarding the large remains that the Smithsonian collected, and the Powell Doctrine specifies that the use of such remains should be "limited".
13. It is reasonable to conclude that use of any such remains in the possession of the Smithsonian has indeed been "limited". They probably have not actually been destroyed, but they are probably deeply buried within the Smithsonian.
14. It is possible that the large remains collected include both Bigfoot and members of the race of exceptionally tall humans.
Where is my logic flawed here?
