CC,
Don't expect a response out of faux Melchizedek here on that one.
Peyote ravings, (Joseph Smith), usually fail in the light of day.
Darn it, and I was all ready to post "Blessings of Exaltation," and "Requirements for Exaltation." Which all but negate the sacrifice of Jesus Christ and his Atonement.
(Never mind me, I am just an "anti.")

Sorry, but I mistook your reference Melchizedek to be a jest of some sort; I did not realize you expected a response.
You wrote:
They think they can attain the same rank as Christ: Man becomes God.
I said that you were misinformed because Latter-day Saints most definitely do not believe that they will ever attain the same rank as Christ. Nor do we believe that man can become God. Doctrine and Covenants 76 expresses it well:
58 Wherefore, as it is written, they are gods, even the sons of God— (D & C 76:58; emphasis added)
Note that men may be called "gods" (lowercase g), meaning the sons of God (uppercase G). This verse alludes to John 10, where Jesus quotes Psalm 82:6:
34 Jesus answered them, Is it not written in your law, I said, Ye are gods?35 If he called them gods, unto whom the word of God came, and the scripture cannot be broken;
36 Say ye of him, whom the Father hath sanctified, and sent into the world, Thou blasphemest; because I said, I am the Son of God? (John 10:34–36; emphasis added)
Thus, the idea that men can be called gods (little-g) is thoroughly Biblical, and is approved by Jesus Christ himself.
However, we do not believe that men will ever attain the same rank as Jesus Christ, much less God the Father. Again from D & C 76:
Note that men belong to Christ, just as Christ belongs to God the Father. Note too that it is God who subdues all enemies, not man. Men cannot exalt themselves; God must lift them up through the Atonement of Jesus Christ. And those who receive all things will always be subordinate to Jesus Christ.59 Wherefore, all things are theirs, whether life or death, or things present, or things to come, all are theirs and they are Christ’s, and Christ is God’s.
60 And they shall overcome all things.
61 Wherefore, let no man glory in man, but rather let him glory in God, who shall subdue all enemies under his feet. (D & C 76:58–61)
All of this is Biblical. The reference to overcoming all things reminds me of the words of Jesus Christ as recorded in the Revelation of St. John:
21 To him that overcometh will I grant to sit with me in my throne, even as I also overcame, and am set down with my Father in his throne. (Rev. 3:21)
I hope that clarifies things.
