one question that's really intriguing and could potentially be evidence that Jesus rose from the dead is the fact that doubting Thomas was skeptical of the resurrection but upon touching Jesus' wounds he became a believer in the resurrection.
First, for Jesus to rise from the dead, or do anything else, in any significant sense, there must first have been an historical Jesus, not just a legendary or mythical one. It's possible there was such a person in history. It's also possible there was not. There's no clincher either way.
Second, for someone to rise from the dead, there must be credible evidence that (a) they had suffered irreversible cessation of the body's life support functions and (b) afterwards they had nonetheless returned to life, a event common in stories but without a single authenticated example in reality ─ note the import of 'irreversible cessation'.
Third, there are six accounts of the resurrection (Paul's, the four gospels', and Acts 1). None is by an eye-witness, none is an independent account, and none is contemporary. The earliest is Paul's brief mentions, and these are written not earlier than twenty years down the track. The second, and the first with any substantial details, is by the author of Mark, about 45 years after the purported event. Matthew and Luke are maybe decade further on, and John, and Acts', around 70 years late. If those aren't sufficient barriers to credibility, in addition each of the six accounts contradicts the other five in major ways.
That's to say, it's no more credible that Jesus rose from the dead than that Osiris, Dionysos, Hercules, Asklepios, or countless others in antiquity rose from the dead; and to establish that there was one such incident requires addressing all the problems above to an extremely high standard, which can't be done ─ the evidence for the resurrection is a forensic disaster.
Now assuming the story is true, unless someone can provide reason to doubt that Thomas existed or reason to doubt that he was skeptical of the resurrection even if he did exist, wouldn't the fact that Thomas was skeptical of the resurrection but then became a believer in the resurrection be potential evidence for the resurrection?
Read the report (John 20:24-29) carefully. You'll notice that in the story, Thomas is invited to touch the wounds, but
he doesn't do so.
Note too that (a) the author of John is writing about 70 years after the purported event and (b) neither Paul nor the other three gospel authors has mentioned any such thing.
