Journal of Discourses, Vol.7, p.285 - p.286, Brigham Young, October 9, 1859 Here let me state to all philosophers of every class upon the earth, When you tell me that father Adam was made as we make adobies from the earth, you tell me what I deem an idle tale. When you tell me that the beasts of the field were produced in that manner, you are speaking idle worlds devoid of meaning. There is no such thing in all the eternities where the Gods dwell. Mankind are here because they are the offspring of parents who were first brought here from another planet, and power was given them to propagate their species, and they were commanded to multiply and replenish the earth.
Journal of Discourses, Vol.17, p.144, Brigham Young, July 19, 1874 This earth is our home, it was framed expressly for the habitation of those who are faithful to God, and who prove themselves worthy to inherit the earth when the Lord shall have sanctified, purified and glorified it and brought it back into his presence, from which it fell far into space. Ask the astronomer how far we are from the nearest of those heavenly bodies that are called the fixed stars. Can he count the miles? It would be a task for him to tell us the distance. When the earth was framed and brought into existence and man was placed upon it, it was near the throne of our Father in heaven. And when man fell--though that was designed in the economy, there was nothing about it mysterious or unknown to the Gods, they understood it all, it was all planned--but when man fell, the earth fell into space, and took up its abode in this planetary system, and the sun became our light. When the Lord said--"Let there be light," there was light, for the earth was brought near the sun that it might reflect upon it so as to give us light by day, and the moon to give us light by night. This is the glory the earth came from, and when it is glorified it will return again unto the presence of the Father, and it will dwell there, and these intelligent beings that I am looking at, if they live worthy of it, will dwell upon this earth.
