My sense is that more we discovered, the more it would impact believers, not non-believers. The most likely scenario is that any new facts that emerged would contradict the Bible. It would be unlikely that actual miracles could be proven.
Or if any were “proven”, they’d turn out to have non-miraculous explanations; some kind of fraud, say. But it’s hard to imagine a realistic way to prove that after so long.
Although some aliens could show up and apologize for the practical joke of their ancestor J’Zuz.
Depends on what you mean by “tremendous”. Compared to what we know about typical folks born in the past century, certainly not. Compared to typical contemporaries of Jesus, though, arguably so.
Isn’t that like saying there is a tremendous amount of evidence for Santa Claus compared to the amount of evidence for the Easter Bunny?
You mean the other messiahs that were running around at the time? If so, then that’s probably true. That said, my confidence in those figures is only justified because, just like Jesus, it seems to me to be the simpler assumption.
There might be proof that a person with the name of Jesus lived. If such a man lived, how would that prove he was the son of god? How would the fact that a man named Jesus lived prove that he died and was resurrected? What solid proof of his divinity do you imagine will ever be found?
Assume that Jesus, as described in the gospels - i.e. an itinerant Jewish preacher in first century Palestine who was executed by the Romans and subsequently became the focus of a cult - actually existed. What evidence of this would you expect to find?
The answer, most historians seem to think, is “pretty much the evidence that we actually have”, and on this basis most historians consider the historicity of Jesus of Nazareth to be adequately established. They do not, for that reason, necessarily become Christians. And if still further evidence became available through, e.g., some incredibly serendipitous archaeological discovery, I don’t see any reason to assume that any more of them would then become Christians.
I suspect that the number of people who aren’t Christians because they are convinced that Jesus never existed at all, or even because they are unconvinced that he did, is vanishingly small. The hurdle to accepting Christianity is not the claim that he never existed, which is a fairly unremarkable claim. It is claims such as that he rose from the dead, that he was God incarnate, and so forth that are hard to accept.
