(c) The information was unnecessary for the time and the audience it was written to
but is was the perfect time to insert scientic fact for the everlasting later audience. like:
In the beginning god created the heavens and 10 billion later the Earth. or:
Jesus: "Your are wrong satan, my brother, only on a flat earth would a higher and higher mountain give me the view of all the kingdoms of the Earth, you are a deluded flat earther. ( if it is just a mental, visionary thing why not do it in a cave? )
The bible is wrong from A to Z except for a handful of passages.
