Inspired prophet Brigham Young taught there was life on the surface of the sun, as well as inhabitants on the moon. One day, when the only true church is independently wealthy enough, the truth about civilizations on the ocean floors and within volcanos will give modern science a new guide that will lead us all to further light and knowledge.
Not only Brigham with the sun and the moon but . .
“ ‘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 & are quite general in Style, or the one fashion of dress. They live to be very old; comeing [sic] 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.”
- Prophet Joseph Smith, Jr., in Journal of O.B. Huntington, Book 14, p. 166
It's also in the D&C: the earth purified into a burning glass ball, a universal seer stone. That's in the D&C, isn't it?
The image is also in Revelation, and earlier in (2nd) Isaiah and Daniel--all books influenced by Persian Zoroastrianism, in which God was fire. This is another area in which JS lifted ideas from apocryphal Christianity and Kabbalah Judaism.
