The Bible is just an abridged, edited collection of first hand accounts, stories and fables, etc.
I read somewhere that the various elements that were being reviewed to create the first "edition" of the bible were massively contradictory, which means that the bible (as we know) it is just one interpretation of what happened during those times.
The equivalent would be a group of "literary elites", some time in the future, taking various selected pages out of the Harry Potter books to create one book that a new religion would then be based on....
How people can put their trust and live their lives based on something like that completely escapes me....
As far as I can tell, most religions are indistinguishable from organised crime.
