That's rather an appeal to extremes - I prefer myself the middle ground, containing truths.
There's no proof God created the Earth in seven days, for example - and to believe such a thing would be considered intellectually dishonest considering the mass of evidence that we have to support the contrary.
- The Tanakh ("Old Testament") is completely independent from the New Testament
- 3. It doesn't have to be "wrong" or made up. Sections of it are most likely historical, but other parts are probably not.
- 4. The Tanakh contains metaphors and historical acts (or pseudo-historical), so why would this not also be for the New Testament?
Either way, a bunch of men (not necessarily Jewish men) wrote the whole thing, over time. Matthew did not pen the Gospel of Matthew, nor did John pen John or Revelation, just like Moses didn't write the Torah (first five books of the Tanakh).
It doesn't make it wrong, but this is what happens when you delve into literalism, you can destroy the beauty of the message.
