The Infinite Atonement by Tad R. Callister pg 242
Shortly before his death, President Lorenzo Snow visited Brigham Young University for the purpose of speaking to the assembled student body. On their way to the assembly room, BYU President George H. Brimhall escorted President Snow through one of the kindergarten rooms. There President Snow saw the children making spheres with clay and said:
President Brimhall, these children are now at play, making mud worlds, the time will come when some of these boys through their faithfulness to the gospel, will progress and develop in knowledge, intelligence and power, in future eternities, until they shall be able to go out into space where there is unorganized matter and call together the necessary elements, and through their knowledge of and control over the laws and powers of nature, to organize matter into worlds on which their posterity may dwell, and over which they shall rule as gods.
