Here. Without a knowledge of what the Papers actually teach, your analysis is less than perfect.
If you did read it, you would probably remember significant aspects of the teaching, philosophy and cosmology, especially
the first 12 Papers which is the core-context and cosmology of the entire revelation in essence. The Papers dealing with certain aspects of history/science/astromony later on in the succession of the papers were taken from human sources and paraphrased/expanded on. The commentaries on religious experience and man's eternal destiny relative to evolutionary progress and divine partnership, remain consistent and inspiring.
I read all 196 papers. I remember most of the main ideas, but I don't claim perfect knowledge, do you?
We were discussing the issue of plagiarism. That the Urantia Book author(s) have committed plagiarism is simply beyond dispute. If we can't even agree on that fact, without evasions such as "Let's assume for the sake of argument," then there's no point in going any further.
There are concepts and there are actual verbal expressions: texts. It is possible to use concepts from others without plagiarizing their words. I asked, "Does the Urantia Book contain truths that could not be conveyed without plagiarizing?" There has been no answer. I believe the answer is no.
Caino mentioned "There was a big lawsuit to break the copyright." He also wrote, "I do gather that the celestials might not be concerned with our man made rules of self accreditation of ideas and ideals in the created universe of our origin."
So let's understand this. The Urantia Book was itself protected by copyright. Whose idea was that? Did that come from the celestial authors, or just the humans of the Urantia Foundation? I'm going to assume that it was an instruction from the alleged celestials. So, we have celestial beings who are cynical enough to demand copyright protection for their own work while violating the copyright protection of others' work. They are apparently quite concerned with our "man made rules" when it comes to their own text. As I wrote above, this casts a large shadow of doubt on the identity and/or character of the authors.
The facts about the book are not entirely irrelevant to the value of its content. That's how it is with books--all books.
I'm not sure why the first 12 papers are supposed to be especially relevant to this. I've had a look at the Block site and I see that he is regularly adding to it. He seems to be working on the early papers now, and has found sources for paper 1. He's done quite a lot of work on papers 100-103, on the nature of religion and religious experience.
Your statement, "The Papers dealing with certain aspects of history/science/astromony later on in the succession of the papers were taken from human sources and paraphrased/expanded on," seems to imply that other content, not dealing with history, science, and astronomy, was not taken from human sources. If this was your intended meaning, it's false.
