The Bible says there is one God who is eternal. Does Joseph Smith, LDS founder, prophet, seer and revelator contradict the Bible?

He said, "In the beginning, the head of the Gods called a council of the Gods: and they came together and concocted a plan to create the world and people in it." Joseph Smith Jr., Journal of Discourses, vol. 6, pg5. He also said, "Sons of God who exalt themselves to be Gods, even from before the foundation of the world, and are the only Gods I have reverence for." (Joseph Smith, History of the Church, vol, 6, Pp. 473-479. One more quote, "We have imagined and supposed that God was God from all eternity. I will now refute that idea, and take away the veil, so that you may see...he was once a man like us... (Smith, Teaching of the Prophet, pp. 345,346.) How do the Mormons reconcile these statements from what the Bible teaches? Mark 12:32, "And the scribe said to Him/Jesus Christ, "Right, Teacher, You have truly stated that He/the Lord God is ONE: And there is no one else besides Him." Or Psalm 90:2, "Before the mountains were born, Or Thou didst give birth to the earth and the world, Even from everlasting to everlasting, Thou are God."
