Why do people believe the Bible to be accurate and without error?

I've got no problem with religion, or with people believing in whatever god, but why do people take books to be totally without error? I've never understood that. Whether it is the Bible, Koran, a science textbook, whatever... doesn't it enter into people's head that a book can make mistakes. If not in the writing, in the translating, or in the interpretation. Two people can read the same thing and come to different conclusions. Misplace a comma here, a letter there, the whole meaning can change. And when you add the fact that the Old Testament was written in Hebrew - a language which does not use vowels, and therefore often words can have more than one possible translation into another language, it is surely very easy for words to be translated or interpreted in different ways.
