Slight correction. Jesus was not a prophet. He was a rabbi. Technically of the Essene branch. Descended of the house of David.
There is some anecdotal reason to think that he existed, aside from faith. "Holy Blood, Holy Grail"

Even though one of the authors refuses to lend any credence to the theory, the long story short is that there is a secret society that started with the Priori de Sion that started not too far from Jerusalem. This secret society had the ability to influence kings and others with a secret. A treasure that was carried on the back of one man during one escape down the side of a mountain.
Essentially, going back to the Priori de Sion led back to Jerusalem about 2,300 years ago.
So, they approached from another angle and read the story that started around that time.
Jesus was a rabbi. Of the Essene school, which explains his simple clothes and a few other things.
A big and important event is the wedding at Canaan. Because of what his mother says, this was likely the wedding of Jesus. It was the groom's responsibility to see to the catering. She tells him they are out of wine. He barks back, "have one of the maids do it. (translated.)"
The likely bride was the one woman well connected to him. Mary of Magdalene. She was not a pro, she was the daughter of a wealthy family.
The only problem and kink in this is that the romans were OCD about keeping records. And there is no record of the execution of Jeshua of Nazareth (born in Bethlehem.)
As a rabbi, he would be expected to be married and have children. "The Last Temptation of Christ" is fanciful and a good movie but not necessarily historically accurate, BTW.
So, here is Jeshua, legitimately of the House of David and therefore, heir apparent to the Throne of Jerusalem. Which is a problem because they are occupied by the romans and not equipped to throw out the romans. This also upset the entrenched rabbis who had a nice little niche getting along with the romans. And they did not need a political bomb upsetting it.
Things got so heated that Jesus had to get gone. And faked his own death. Some of the apocrypha, testaments excluded from the Bible at the council of Nicae, mentioned that the crucifixion happened on the private property of the guy known as Joseph of Aramethea. And that crowds were not allowed to get close.
So, Jesus and Mary and their children escape and sail around the Mediterranean and land finally in the southern type of Gaul and then the children married into one of the established family lines, the Merovingians. Here is a fun thought. Somewhere near Paris, France today exists a living descendant of Jesus Christ. Who would be heir apparent to the Throne of Jerusalem. A messiah, as in, a priest-king.
That could cause a problem. Even now with Israel at war with Hamas.
None of this proves or disproves the physical existence of Jesus, God, or even mono-theism.
Just wanted to clarify that He was/is not a prophet.
