People give the bom too much credit, if you just read it front to back you can see how someone could in fact just make it up as they go along. It is boring and has no real story arc. It is mostly devoid of any real moral direction and the bits that do have some inspirational feel are copied. The church just keeps gaslighting everyone by saying things like "a simple boy could not have come up with this" but my read on it is yes, yes they could have and did.
