Obviously, they all can't be the word of God since they all contain different words and different truths. God cannot contradict Himself.
Given your statement, you must believe that which was not the word of God somehow became the word of God when it was published in 1611. That is effectively transubstantiation of the Bible, and it isn't consistent with the Bible.
Again, if the KJV was translated/adapted from that which was not the word of God (previous English and Greek editions), how can it be the word of God? You are the one who effectively affirms this, so please consider and answer it.
I don't get my theology from the thoughts of man in the preface of the KJV, but from the words contained within. Because they did not claim God's hand in translating the Scripture does this mean that God could not be or was not in control of their commission?
This isn't a matter of theology; we aren't discussing the nature of God. Your position is logically and historically untenable, and instead of thinking through the implications of it, you are avoiding the issue with a redirect. It isn't going to fly. While I can accept your reasoning in your last sentence above, you must also recognize the inverse: it doesn't mean God was involved (to the degree you claim) either.
For the answer we must look to the Bible, our final authority in all matters of faith and practice. When John the Baptist was accosted by the Levites in John chapter one and asked if he was Elijah (John 1:21) he answered that he was not Elijah. Yet in Matthew chapters 11:7-14 and 17:10-13 Jesus Christ plainly stated that John was Elijah. Did John the Baptist lie? No. Did Jesus Christ lie? Of course not. The answer is very simply that John was Elijah but he didn't know it! Thus we see from our Bible example that a man can have God working through him and not know it. Likewise, God could easily have divinely directed the King James translators without their active knowledge.
You are basing your argument on your speculation that John did not know his role. While that is plausible, it is not certain. John could have known his role quite well, and still answered truthfully, because until Jesus stated that John was the Elijah who was to come, the Scripture they knew declared that another was to come "in the spirit and power of Elijah". That didn't make John a resurrected or returned Elijah; he was still John, but he fulfilled that prophecy nonetheless. Truth can have more than one level.
If your "theology" is logically untenable, the problem is not with logic.
