This thread contains too many half-baked generalizations to shed any light. To be sure, those who do not wish to believe that the Bible is the Word of God can find a million "reasons" for that disbelief. But if the disbelief is supposedly based upon scholarship, it is wise to get the facts correct.
For example, one of the reasons was:
"2) The written Hebrew was composed entirely of consonants, without any points or marks standing for vowels, so that anything like accuracy was impossible, Anyone can test this for himself by writing an English sentence, leaving out the vowels. It will take far more inspiration to read than to write a book with consonants alone."
Wrong! It does not compromise accuracy or understanding that Biblical Hebrew was written without vowels. Modern Israeli Hebrew is also written without vowels, and millions of people understand and use it with precision and accuracy just fine. It is the language of literature, politics, and everyday life in modern Israel. Because it is a living language, people don't need the "vowels," though in some cases -- as in Biblical Hebrew -- certain consonants also do double duty as "vowels." And while Biblical Hebrew was still a living language, it was translated into Greek, which does have vowels. Therefore, the Greek translation (the LXX) can offer some assistance in understanding obscure Hebrew Biblical terms.
Remember, too, the example of the Dead Sea Scrolls. Though nearly 2,000 years older than the standard Hebrew Masoretic texts of Isaiah, over nearly 2,000 years of transmission by copyists, the DSS text is virtually identical with the Masoretic text. In view of the time, what few variants in spelling do exist -- none of which affect basic understanding or teaching -- are simply remarkable. One might even say "divinely" protected.
There are similar flaws in all the points you have presented. But I will not go into them here, for in truth, entire books have already been written on these matters, containing excellent positive research.
