Joseph Smith 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 1,000 years. He described the men as averaging nearly six feet in height, and dressing quite uniformly in something near the Quaker style.

LDS advocate Van Hale said:

“But all things considered the possibility, or probability, that he did [believe in moonmen] cannot be reasonably denied.”

Brigham Young said:

“Who can tell us of the inhabitants of this little planet that shines of an evening called the moon? … when you inquire about the inhabitants of that sphere you find that the most learned are as ignorant in regard to them as the ignorant of their fellows. So it is in 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.”

Brigham Young – 24 July 1870, Journal of Discourses – Volume 13 (Liverpool, England: Horace S. Eldredge, 1871), 271.

Some LDS apologists claim, in fairness to Joseph Smith: Science has yet to prove men do not inhabit the moon.​
