However, the Bible's writers never saw each other's writings!
I sometimes wonder if we are reading the same books. Last time I checked, the books of Moses are often referred to by later books. Luke 20:42 mentions the Psalms, as does Acts 1:20. It is obvious from what is being said that they have read each others works, as well as other works which are either lost or not considered divine.
Hopefully, that is not the reason you are impressed by the collection of writings. A simple look at evidence shows it to be false. Oh evidence, how I love thee
I actually came into the thread because I was curious as to what the topic was. It started off with a piece of spam that has been circulating for decades (usually the student is revealed as being called Einstein or some crap), and now we are talking about the necessity of the divine or mundane origins of a collection of short books and the evolution of life? Maybe I missed it - what is the actual topic?
