Bro McVos, I will just sum up my answers to everything you said.
As I’ve said, Muslims did not totally reject that the bible might contains some truth in it, like the first law of the Ten Commandments and Jesus affirmation of it as the most important commandment second the story of creation though the Qur’an clearly states it differently. When you said, “many stories of the Qur’an are derivatives of the bible”, these are just the affirmation of the some truths that can still be found in the bible. In addition to that, many scientific accounts in the Qur’an which cannot be found in bible that science of today confirms its authenticity. Muslims prove these scientific accounts when they developed many branches of sciences which we still enjoy today like medicine, mathematics, chemistry, geometry, astronomy and many others, these are all happens when the Muslims rules Spain for almost 8 centuries when most of Europe is in the Dark Ages and this is the most important factor that triggers the Renaissance of Europe, this era was considered by all believers as the Golden Age. Now back to the Bible, authenticity of the writers are questionable, I have yet to see a countries or even a country or most even a barangay that the Bible is the fundamental basis of laws in the land because it cannot stand. But I can tell you a country or countries that the Qur’an is the fundamental basis of laws in the land. When the Christians prayed “… Hallowed be Thy Name; Thy kingdom come, Thy will be done, on earth as it is in heaven” the Muslims are the one doing these; they make the words of God the fundamental laws of the land. Moreover, we can point many inconsistencies and discrepancies in the Bible, The Jehovah's Witnesses in their "AWAKE!" Magazine dated 8 September, 1957, carried this startling headline — "50000 ERRORS IN THE BIBLE?" see link;
IS THE BIBLE GOD'S WORD? - By Ahmed Deedat. Now is the Bible God’s Word? That’s a big question, you have to prove it! Prove also that all Christians can be one in believing one version of the bible; not KJV, not Douay Rheims, not New International Bible and many more bible versions that scattered all around the world.
