Men On The Moon

As incredible as it may seem, LDS publications bear testimony that Joseph Smith, founder of the Mormon Church, and Brigham Young, second Prophet of the Church, taught the moon was inhabited. In an 1892 LDS publication under the heading "THE INHABITANTS OF THE MOON," this interesting information is given by Oliver B. Huntington.
"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)

Huntington also told of founding prophet/president Joseph Smith’s teaching regarding the moon:
“The inhabitants of the moon are more of a uniform size than the inhabitants of the earth, being about 6 feet in height. They dress very much like the quaker style and are quite general in style, or fashion of dress. They live to be very old; coming generally, near a thousand years.” This is the description of them as given by Joseph the Seer, and he could “see” whatever he asked the father in the name of Jesus to see. The Journal of Oliver B. Huntington, Volume 3, Page 166

Here's Brigham Young's statement:
Oliver B. Huntington recorded in his diary:
"The inhabitants of the moon are more of a uniform size than the inhabitants of the earth, being six feet in height. They dress very much like the Quaker style and are quite general in style or fashion of dress. They live to be very old; coming generally near a thousand years. This is the description of them as given by Joseph [Smith] the Seer, and he could see whatever he asked the Father in the name of Jesus to see" - Journal of Oliver B. Huntington, Vol 2, p 166, emphasis added from Brigham Young:

"I will tell you who the real fanatics are: they are they who adopt false principles and ideas as facts, and try to establish a superstructure upon, a false foundation. They are the fanatics; and however ardent and zealous they may be, they may reason or argue on false premises till doomsday, and the result will be false. If our religion is of this character we want to know it; we would like to find a philosopher who can prove it to us. We are called ignorant; so we are: but what of it? Are not all ignorant? I rather think so. Who can tell us of the inhabitants of this little planet that shines of an evening, called the moon? When we view its face we may see what is termed "the man in the moon," and what some philosophers declare are the shadows of mountains. But these sayings are very vague, and amount to nothing; and when you inquire about the inhabitants of that sphere you find that the most learned are as ignorant in regard to them as the most ignorant of their fellows. So it is with regard to the inhabitants of the sun. Do you think it is inhabited? I rather think it is. Do you think there is any life there? No question of it; it was not made in vain. It was made to give light to those who dwell upon it, and to other planets; and so will this earth when it is celestialized. Every planet in its first rude, organic state receives not the glory of God upon it, but is opaque; but when celestialized, every planet that God brings into existence is a body of light, but not till then. Christ is the light of this planet." - Journal of Discourses Vol. 13, p.271.

Oliver B. Huntington, who was a close associate of Joseph Smith and remained a faithful Mormon his whole life, had this to say:

Astronomers and philosophers have, from time almost immemorial until very recently, asserted that the moon was uninhabited, that it had n atmosphere, etc. But recent discoveries, through the means of powerful telescopes, have given scientists a doubt or two upon the old theory. 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 a 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.
