Jesus Christ as depicted in the Bible, with near 100% certainty never existed. He was no more real than Harry Potter.
The absolute lack of evidence of existence for a person claimed to be the most significant person that ever lived, and who performed numerous miracles, means that the only reasonable conclusion is that he never actually existed.
It would be like if we had zero evidence for the existence of Cleopatra, outside some scriptures written by a superstitious sect, where the earliest were written 2 generations after her death, by anonymous authors, and based only on hear say, and written in a place that it would take weeks to travel to or even months. With zero contemporary or first hand evidence.
And then imagine Cleopatra performed miracles regularly too.
AND Cleopatra lived 1 generation before Jesus, and 3 generations before the first "books" of the new testament were written.
But in difference to Jesus, there are loads of historical evidence that Cleopatra lived. When she lived, where she lived, and who she was. But not only her, also her family, like father and brother are well documented, and several events Cleopatra was part of are also very well documented.
Add to that that the search for evidence for the existence of Jesus is probably the by far biggest historical and archeological search in history. Spanning almost 2000 years, with massive financing from wealthy Churches especially the Catholic and Mormons have spend insane amounts of money searching for evidence, but not only that, also traditional historical institutions have participated, because they too, despite the absolute lack of reason for it, thought that there ought to be evidence for the existence of Jesus.
This search we know for sure started already in year 200!! And it was pretty intense for more than 1500 years!!! And the search often included scholars, because they too were deluded.
And their combined efforts have turned up nothing but fakes created after the fact. Zero actual historical evidence.
The few pieces (about 3) some claim are evidence are heavily refuted as obvious fakes too.
