The God of Mormonism is an exalted man with a body of flesh and bones:
God himself was once as we are now, and is an exalted man, and sits enthroned in yonder heavens! That is the great secret. If the veil were rent today, and the great God who holds this world in its orbit, and who upholds all worlds and all things by His power, was to make himself visible, — I say, if you were to see him today, you would see him like a man in form…’ (King Follet Discourse, Joseph Smith, History of the Church, volume 6, p305)
The Father has a body of flesh and bones as tangible as man’s. (Doctrine and Covenants 130:22)
The God of Christianity is not a man:
For he is not a man, as I am, that I should answer him, and we should come together in judgment (Job 9:32);
But a Spirit:
God is a Spirit: and they that worship him must worship him in spirit and in truth (John 4:24);
Who does not have a body of flesh and bones:
…for a spirit hath not flesh and bones… (Luke24:39).
Nope, not the same God at all.
Consider also these points made by Jon Dykstra to Glenn Beck:
Christians believe that Jesus was never created but Satan was; Mormons believe both Jesus and Satan are created beings.
Christians believe that Christians are adopted children of God and in that sense are brothers and sisters of Christ; Mormons believe all created (sentient) beings are spirit children of the Father and thus not only are we brothers and sisters to Christ but so is Satan.
