Klingon maybe?
Some alien race, anyway...How else would Brigham have had the "inside track" on such info as "moon men":
Lds "prophet" Brigham Young: 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 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.
Source: Journal of Discourses, Vol. 13, p. 271...1870 -- so keep in mind, Young had already been leading the Lds church for about 25 years or so when he made this comment.
BTW, where did Brigham Young get his "source" re: the habitation of the moon?
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 near the age of 1000 years. He described the men as averaging nearly 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 not behold with your eyes. The first two promises have been fulfilled, and the latter may be verified. From the verification of the two promises we may reasonably expect the third to be fulfilled also.

I think the sci fi show of the 80’s with lorne green was based on the Mormon faith. Google it. Today I went to a Mormoun temple to support a friend whoms daughter is about to go on a mission. I could care less what he celebrates on Sunday. I hope people feel the same way of the Catholicism we practice. Everyone was really nice. Its America, the Puritans came here to escape religious persucution.
A “elder” asked us if we are “investigating”. I politley said no. That was the end of it. Nice folks. We were treated with well manors and smiles.
