Like with the elephants, the Smithsonian experts are sure no tribe in America had a language – ever:
…whenever an alphabet of any kind is veritably discovered, it must have had a foreign origin. By granting belief to anything contravening this state of art, we at first deceive ourselves, and then lend our influence to diffuse error. – Schoolcraft (John Campbell “The Ancient Literature of America,” Proceedings and Transactions of the Royal Society of Canada, Second Series, Vol. II, 1896, pp. 47)
- “Charactors” copied from the gold plates
- The Ancient Literature of America by John Campbell, LLD – 1896
- Ancient Man in America Including Works in Western New York and Portions of Other States, by Frederick Larkin, M.D. – 1880
To admit that even a single tribe in North America had a written language would upset established thought.
