Yes, the bible itself claims this (2 Peter 1:21). I was referring to men coming up with the idea and colluding over a millennia.
> Many of the story elements and arcs can be found in cultures that pre-date Christ.
That is because everything in the New Testament (including Christ's life) was an extension of what had already be told for thousands of years earlier.
> Over thousands of years one can find examples for any broad prophecy.
These aren't broad prophecies. They are specific accounts of events such as the destruction method of Tarshish by a Greek commander (Alexander the great) or the name of a future Persian King who would command the rebuilding of the temple (Darius the Persian) or the return of Israel as a nation after Daniels 69 weeks had elapsed, etc...
The most extensive prophecies are focused on Jesus himself and what he would do and how he would die (Isaiah 53, etc..).
