First of all, those 'original manuscripts' you are talking about were probably first written on papyrus, a substance that corrodes easily. Paper as we know it was not invented until much, much later. Yes, we do not know what was written on those original manuscripts. But we have a pretty good idea. So let me see if I understand you correctly: you believe nothing (?) in the Bible? There are some people who do not, so I've heard that before, meaning they don't even believe Jesus existed because frankly, outside of the Bible, there's not that much evidence he existed. Oh, and yes, because of the many names, dates, and places mentioned, including wars and kings, yes -- it is too detailed to have been made up, that is, in my opinion, of course.
