Examples of how they fit my understanding laid out above

The Torah: How the Earth came about, why it came about, and the best ways to live in society governed by the first two. God, someone made in our image (we're the most intelligent beings we knew of, it was actually good science to believe without more proof that God would look like us), made the world, put us in charge purposefully (as we operate purposefully) and now here are some things that will keep society from falling apart. And you HAVE to do them because God said so (makes sense, keeps things simple and in order)

The Prophets: Why the fuck is everything so bad for the Jews? Because of something that will happen in the future, so don't give up faith. This makes sense given the context of the Torah and given the need to not give up hope.

The New Testament: The prophets said we'd have a savior, and he delivers: but only in the way he could. Leading a military uprising wasn't feasible at the time, but leading a spiritual one was: hey guys, given the context of the Torah and the Prophets, we're going to have a revolution but not of this world. Of the next.

So we've replaced many of the understandings that, dozens of centuries ago, made sense.
