Hey, I’m just asking a good natured question! But, if you’d rather talk about Mormons, planets and underwear!
Mormons do believe in theosis, as do the Greek Orthodox. As far as having one’s own planet? I think galaxy or universe would be more accurate. If this universe is just one of billions, then is it run by just one being we call “God”? What if God is a collective, as is the word “Elohim”? Or the word “family”? Or “quorum”?
“Man has become as one of us,” God said in Genesis. What’s this “us” business? If Jesus is God, and the Father is God, and the Holy Spirit is God, then there are three Gods as part of the collective. Each is separate, distinct, capable of speaking to one another. As one early churchman said, “Cattle beget cattle, horses beget horses, and we call ourselves the ‘Children of God.’” So what does a God beget? Theosis or deification is not a new doctrine nor is it a unique Mormon doctrine. Neither the Greek Orthodox or the Mormons state we will have a planet.
And how about our “magic underwear”? That’s not new, either. In ancient temple rites and practices, holy priesthood garments are commanded of God. (See Exodus 28 and this article, Sacred Vestments.) And our underwear have a rich tradition in religious history and theology.

Hmmm. How do you suppose Joseph Smith knew about all this? He didn't get it from ancient sources, but through revelation.
