"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 the one 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 History of Oliver B. Huntington, p. 10
"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 most ignorant of their fathers. 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. 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."Brigham Young, July 24, 1870, Journal of Discourses 13:271
Since it has long been proven that no one lives on the moon (or the sun) this is just another example to demonstrate that neither Joseph Smith nor Brigham Young were prophets of God!
