Beniguman,
So according to what you are saying we have a book written by men who make a claim that it was dictated to them by God. The Koran and many other relgious books make the same claim it is hardly a unique claim for a religous book to make.
That someone claims that a book they wrote was inspired by God is not evidence that it was.
If I write a book and claim that God inspired me to write it, that is not evidence that he did; and in fact most reasonable people will not believe me, UNLESS I could bring you very compelling evidence that it was, but the burden of proof would be totally on me.
Again the prophecies you mention are very vague and broad and are standard issue threats of punishment for disobeying God and promises of being taken care of if you follow his word.
You agree that the first and reasonable conclusion you have when you find a book is that it was written by men
You agree that evrey other book that has been claimed to be divinely inspired is in fact not divinely inspired.
You want me to believe that this particular book is different and was in fact dictated by God.
Can you provide any evidence?
