The Adam–God theory refers to a speculative idea taught briefly by Brigham Young, in which he suggested that Adam occupied a uniquely exalted role in humanity’s relationship to God, language that later readers interpreted as equating Adam with God the Father. LDS critics often present this as binding LDS doctrine, but that is untrue. The theory was never formally canonized, was inconsistently articulated even by Brigham Young himself, and was not adopted in official church scripture, temple ordinances, or sustaining votes of the Church. Subsequent Church leaders explicitly rejected the Adam–God interpretation and reaffirmed the standard LDS teaching that Adam is a created being, the first man, and the archangel Michael, distinct from God the Father. When viewed in context, the Adam–God theory reflects speculative theological exploration during a formative period of LDS history rather than a doctrinal teaching, and it does not represent the beliefs of the Church today. 

"We warn against the dissemination of doctrines which are not according to the Scriptures and which are alleged to have been taught by some of the General Authorities of past generations. Such, for instance, is the Adam-God theory. We denounce that theory and hope that everyone will be cautioned against this and other kinds of false doctrine"                                                                                                 -Spencer W Kimball
