Also, history is written by the insane, as I have seen.
To use your words, Yeah, no, I'm gonna need at least every single historian in the world agreeing on that one for that to even be in the slightest convincing.
And since when did we appeal to authority/majority like that? And I don't recommend out-of-hand dismissals, there are just about as fallacious as blind faith (believing without checking the evidence)
When was science done like this? I am going to need every single scientist on the world agreeing for instance on climate change to be the slightest convincing.
I don't think history or studying historical* literature is any different.
So I am afraid, your expectations may be a bit unrealistic.
*or other forms, in case you dispute my usage here.
In the case of the resurrection which I suspect your original quip was in response to.
Biblical scholar Géza Vermes analyzes this subject in his book, The Resurrection. He concludes that there are eight possible theories to explain the "resurrection of Jesus". Vermes outlines his boundaries as follows,
"I have discounted the two extremes that are not susceptible to rational judgment, the blind faith of the fundamentalist believer and the out-of-hand rejection of the inveterate skeptic. The fundamentalists accept the story, not as written down in the New Testament texts, but as reshaped, transmitted, and interpreted by Church tradition. They smooth down the rough edges and abstain from asking tiresome questions. The unbelievers, in turn, treat the whole Resurrection story as the figment of early Christian imagination. Most inquirers with a smattering of knowledge of the history of religions will find themselves between these two poles."
From his analysis, Vermes presents the remaining six possibilities to explain the resurrection of Jesus account,
(1) "The body was removed by someone unconnected with Jesus",
(2) "The body of Jesus was stolen by his disciples",
(3) "The empty tomb was not the tomb of Jesus",
(4) Buried alive, Jesus later left the tomb", (a variant on the swoon theory)
(5) Jesus recovered from a coma and departed Judea, (another variant on the swoon theory)
and (6) the possibility that there was a "spiritual, not bodily, resurrection".
[I will also add there are more, if you consider Islam's view of the death of Jesus as not occurring at all]
Vermes states that none of these six possibilities are likely to be historical.
(1) is speculative, (2) is the claim documented as being held by the Jews, which is if you are really really optimistic, plausible.
(3) I will just say very quickly, that the whole thing was fairly public, a public execution. So we have no evidence for this claim, and we have evidence that suggest otherwise.
(4) and (5) I can discredit if needed, in either detail or in a short reply. (5) is held by some other faiths.
(6) is held by liberal Christians, but it seems inconsistent with the testimony of the disciples.
(7) I highly doubt, evidence suggests the contrary.
