you have quoted various bible "contradictions" that have all been pointed out, and accounted for in modern biblical critisism. The answer to the problem lies not in true 'contradictions' but rather in errors in interpretation.
Since we have ancient manusripts to review, and correct our translations, we can be certain to avoid mistakes. The most accurate translation is the New American Standard, and I think you will find most of your "contradictions" are not present. The reason?? Simple..better scholarship in translating the ancient manuscripts.
On the otherhand, the Quran has huge problems that are not so easily reconciled.
You may want to know that the issues you have brought up are old, and have been satisfactorily answered many times and in many publications. In fact, the 'contradictions' have been explained to the satisfaction of scholars who are both Christian and secular, so you may not say that the answers are a convenient brush off, that only christians would believe. That is not the case. You have not brought up any new revelations, and the errors are only in translation, not in doctrine.
You will find the Bible front to back, NEVER contradicts itself on doctrine, whereas the Quran is full of contradictory doctrine....sir, you have been led astray, please reconsider and do further study, not from a biased standpoint...all the info you have posted comes from standard muslim propaganda sites and is far from original.
God Bless
