1. All i can say to this is that you need to do more research on the history of the bible, you don't strike me as having done much. And really, how can you call it harmonious? It is full of contradictions & multiple themes.
2. Most of the prophecies were either self-fulfilling or were written about after the event (such as in the case of Babylon) & many of them probably never came true anyway (Jesus anyone?).
3. Which morals? Taking a child outside to be stoned for being disrespectful? Not planning ahead but merely focusing on the here & now? Not wearing mixed fabric clothes? Be specific. Many of the better morals in the bible (such as the golden rule) pre-date the bible by hundreds to thousands of years.
4. I'm beginning to think that this thread is satire. Is it? If it is then you should have made that more clear. And really, go & get a decent science book, read it from start to finish, then re-read the biblical sections relating to science & then get back to me. Much of the bible is scientifically inaccurate (bats are fowl?, birds appeared at the same time as fish?, the earth was created before the sun?, the earth hangs on nothing AND has pillars, corners & the heavens have windows?) & as for the parts that are accurate, most of those things were already known by the ancient egyptians 2000 years before the earliest parts of the bible were written. People were not as ignorant back in those days as you might think.
5. How do you know they were being honest? Since much of what they wrote isn't consistent with history, it seems that calling them honest is an odd thing to do, they were either dishonest or misinformed. And if you're referring to people like Moses being honest about his own failures... hmm, check out the REAL history of the Torah, it wasn't written by Moses. In fact, Moses may not have even existed.
