Sadly, desperate people, looking for instant validation and gratification have historically written stories to explain their world. I never claimed that any hallucinated. I think, historically, there have been claims that or 2 hallucinated, but I'm no expert on that. I think they recycled stories, imagined, and filled in gaps in order to give themselves and others something immediate.
So instead of any proof that what they wrote was accurate (and the threads discussing whether the accounts were written contemporaneously with the events, or whether there is any valid external corroboration abound) you want me to provide texts that say that a later invention didn't happen? If someone, in 50 years, claims that in 2020 there were rainbow goats from the moon, will you be faulted for not saying in 2020 that there are none? That's a backwards demand.
Except it doesn't. I mean, I could ask you to explain why the Medrash about how miracles were performed is wrong, or why Rashi's claims on Yoma 10 are inaccurate. How does that sound?
Except that Jesus isn't the Jewish messiah and most of the spread of Christianity was by threat.
What is "deconvert"? If you are saying that my attitude about your religious choice isn't convincing you to go back to whatever idea of Judaism you think you had, then say so. Since Judaism (if you were ever, indeed, Jewish) doesn't recognize "converting" out of Judaism, there is no notion of "deconverting."
Muslims find Muhammed's actual name in biblical text (that's something that Jesus followers can't do) and here are some other points to consider

As for Joseph Smith, here

No doubt you will look at their claims the same way I look at yours.
