Would knowing the provenance make you any more able to believe the miracles? As Wiki says, and despite (as you claim) having unknown provenance, the baptism of Jesus by John the Baptist, and the death of Jesus at the hands of Pontius Pilate, are widely accepted as historical by scholars. So again, when it comes to the miracles it isn't a matter of provenance, but internal evidence like I gave in 46509 that counts.
Even more stupid, Spud.
Sadly I'm not surprised that you probably can't see that what you've posted here is utter nonsense. For instance, what would 'evidence' for a miracle actually look like, and if you had robust 'evidence' acquired via a stated and appropriate method would it still be a miracle? An 'explained miracle' is an oxymoron.
You still haven't told me on what basis you've excluded the risks of mistakes, bias or outright lies in the NT accounts, but of course you can't since you know nothing about the provenance: if you don't know for sure any details about who wrote certain bits originally, or to what extent there have been revisions, and by whom, then in effect you really know nothing that can be accepted as being reliable.
That the NT may contain certain facts: such as that it is a fact that there was, and is, a place called Jerusalem but that does not imply that the bits about a dead man not staying dead are also facts.
