So it is true that you claim that the God of the OT was once a man who grew into His Godhood?

Please expand your understanding.
It sounds like you almost have it, but have left some things that could be misused if not better defined by you showing your understandings of our teachings.
okay you asked
You believe that your god is not the God revealed to us in the bible. You believe that your god was once a man who "attained" Godhood. Since your theology is at odds with the theology of both the Old and New Testament, you (Mormons)decided that you need to dismiss God's Word as "corrupt" although God promised to never let His Word see corruption.
As revealed in the bible, God is a Spirit who cannot lie, yet you (Mormons) say that God lies and is a man.
Furthermore, you cannot then believe in the revealed Plan of Salvation if the bible is "corrupt" and/or not interpreted properly. And that's just for starters.
