If they disregard reports out of hand, then they’re not much in the way of scholars.
I don’t think it’s unreasonable to imagine that a historian would disregard out of hand reports of events such as somebody walking on water or raising the dead. I think these kinds of events would be regarded as matters of faith and not of reliable historical record. I think one would have to say that the Gospels at best attest the fact that Jesus’ contemporaries or near contemporaries believed that he had done these things.
Did anyone witness it or provide eyewitness testimony? ‘Cause… that’s what we have with Jesus’ miracles.
I think you overestimate the historical reliability of those accounts. Take the transfiguration, for example. It is said that it was witnessed by three people. The two of them who later left written sources (Peter and John) only allude to the event in vague and ambiguous terms. The three Gospels that describe the event in detail were at best written by people who knew people who had been there. Or take the resurrection. In the different accounts Jesus appears first to Mary Magdalene, possibly with one or two other women, and in some accounts the resurrection is first announced by one or two angels. None of the women who first witnessed the resurrection were among the authors of the Gospels. Possibly they knew one or more of the authors. I wouldn’t say that that sounds like a particularly reliable eyewitness account.
Error creeps into historical records very quickly. Take the controversy over
The Tattooist of Auschwitz. The author, Heather Morris, based her novel on interviews of the main eyewitness to the events described, Lali Sokolov. The interviews took place three times per week for three years, a total of around 450 interviews. The book is a few hundred pages long, so one or two interviews per page. Morris was able to employ scholars to check facts against archive materials and a massive body of scholarship. Nonetheless, her book is riddled with errors to the extent that it has been dismissed as virtually worthless as a historical document. For example, a key part of the plot (the basis of a subsequent book) is the contention that a senior SS officer openly conducted a relationship over several years with a female Jewish prisoner. It is alleged that Sokolov was an eyewitness to these events. But professional scholars say that it cannot possibly be true. For one thing, the SS officer would have been convicted of racial crimes, dismissed from his position, and sent to almost certain death on the eastern front. Furthermore, the building in which the relationship allegedly mostly took place was in fact never put into use as it was only completed towards the end of the war shortly before the camp was liberated.
The Tattooist of Auschwitz was written about 70 years after the events it describes, has the advantage of eyewitness testimony, archive material, and an abundance of historical scholarship, and describes events that are not inherently implausible, and yet it turns out to be fundamentally unreliable.
