In 1892 Oliver B. Huntington wrote:
“Nearly all the great discoveries of men in the last half century have, in one way or another, either directly or indirectly, contributed to prove Joseph Smith to be a Prophet.
“As far back as 1837, I know that he said the moon was inhabited by men and women the same as this earth, and that they lived to a greater age than we do — that they live generally to near the age of 1000 years.
“He described the men as averaging near six feet in height, and dressing quite uniformly in something near the Quaker style.
“In my Patriarchal blessing, given by the father of Joseph the Prophet, in Kirtland, 1837, I was told that I should preach the gospel before I was 21 years of age; that I should preach the gospel to the inhabitants upon the islands of the sea, and to the inhabitants of the moon, even the planet you can now behold with your eyes.” (The Young Woman’s Journal, published by the Young Ladies’ Mutual Improvement Associations of Zion, 1892, vol. 3, pp. 263-64)
Joseph Smith said it. Oliver B Huntington had faith in what Joseph Smith proclaimed as fact.
Is Huntington's faith in what Joseph Smith said "evidence" that there are Quaker-dressed men and women that inhabit the moon?
If not, why would a Mormon's belief in anything Joseph Smith said be evidence of the proposition?
