The fact that a man named Yeshua, who likely had an affiliation with the Essenes and claimed to be a Jewish Messiah, existed is not a controversial claim in academic circles.

The existence of this man does not mean that he was a divine figure, nor that he performed miracles. He, like John the Baptist, was one of many such figures acting in response to the Roman occupation of Judea and subjugation of the Jewish people at that time.

Claiming that he did not exist is pseudohistory.
