Judging the value of, for one, the Holy Bible is impossible because, with one exception, we have no idea who wrote the various essays in it.
The Old Testament is completely anonymous, so the chapters have the same status as unsigned documents you might find in the street. You wouldn't know whether they were written by truth-tellers or liars, historians, fantasists or propagandists.
The only NT author who can be identified is Paul (Saul of Tarsus) who wrote some of the epistles attributed to him. The rest of the NT is, again, anonymous.
You can believe these things from pure faith, of course, just as you can believe, if you want to, the stories of the Greek and Roman gods or of Snow Whute.
cupid 04, would you like to elaborate? Mere assertions like that get us nowhere.
