The Bible is the claim, not the evidence

[Sword of Christ]

Only if you read it with that bias. You can find differences in style and substance from the first three chapters in Genesis, to say nothing of the many contradictions throughout the texts, which helps some scholars to learn the motivations behind the stories and how the mythology was constructed.

That would be expected to some extent if you have different authors living at various different periods of history. It's not too bad considering though. It certainly has a good level of general coherence, though there was some selective editing in what they choose to keep and reject from the canon.

And that's to say nothing of the complete change in the figure of god from the OT (where he is the "god of armies" and a strict and violent disciplinarian) to the NT (where he masks his expansion of "thoughtcrime" behind a benevolent and peaceful facade).

Jews have a belief in much the same supreme God/power as Christians minus a couple of books about Jesus. You could even say Muslims believe in much the same God as the Bible. Personally I would say the addition of Jesus and the exclusion of Mohammed is the better revelation of the three but faith is going to vary. The core concept of God at least is a commonly shared strand of belief in all the Abrahamic faiths.

There is no question that the Bible was "developed over time" and "assembled at a much later date." But that works to undermine the idea that it's the word of a divine creature who is intensely concerned with our fate and well-being.

Well the revelation of God was through a chosen people who were living in real history and this took place over a lengthy period of time, so what else would you expect?
