Do Mormons believe God is from another planet?

Mormons have no particular notion of where God came from; however, unlike traditional Christians, Mormons do not believe that God has always been God. In June of 1840, President Snow declared, "As man is, God once was; as God is, man may become" (known as The Snow Couplet). From this one may infer that God somehow became God. That at one time He was less than He is now. Just as Christ grew and progressed during his lifetime on earth, the Father also passed through some manner of progression until He became our Father and our Creator.

Some members of the Church believe that God is an exalted man, meaning that he once was a mortal man living on an earth like this one, but others think this is reading too much into the Snow Couplet.

Still others go so far as to believe that our Heavenly Father and his wife live on a planet called Kolob. They have sex and produce spirit children. These spirits are sent to earth to give life to human babies. Some even believe that there are many, many gods with their own planets who produce spirit children, and the Our Heavenly Father is just one of many who progressed from mortal man to divine god. Some even believe that if they keep the commandments, they can become gods and goddesses, create worlds, and produce spirit children to send to their own earth, but this is REALLY reading A LOT into the Snow Couplet.
