As an agnostic, I don't know if he existed.
But indications are at the very most he might have been an eloquent yet very mortal man. Maybe a Essene or a Nazarene. Nobody knows for sure.
Other indications are the Roman Flavian dynasty created the New Testament.
Maybe someday the truth will be known.

Gilgamesh was real, but there is no evidence of him actually fighting the Bull of Heaven.

Christ mythicism is based on the available evidence.
It doesn't matter if you don't believe it, unless of course you would like to believe as many true things and as few false things as possible.
From pre Pauline Christian doctrine to Paul's narrative to the gospels to the apocrypha, mythicism considers all forms of evidence about a Christ. Including Tacitus and Josephus entries.
Vocal? You've got to be joking.

If jesus was real, then the person claiming so, has to prove it. If you claim jesus was not real, then you have to prove it.

I believe he was heavily fictionalized but I believe a Jesus figure MIGHT have existed.

I think Jesus did exist and he was a metaphysic and hypnotist. He performed what were seen as miracles but nowadays is considered mind control. His stories were embellished and took on a life of its own kinda like how big the fish was that broke your fishing line. People believed in the myth until Constantine saw he could use the story to control the masses

I certainly do not deny the existence of Jesus. He is an historical figure. What I do deny is the structure the whgite MEN built around him to keep others in submission, poverty and misery. It serves only the powerful.

It does not matter to me whether there was ever a flesh and blood Jesus. If there was, he was just another man and was used for the basis of phony claims based on legends. If no man existed, he was fabricated from the same legends. If there was a man, he was so unimportant at the time that nothing was written about him.

I don’t deny the existence of a man who was called Jesus. I simply don’t believe that he was a deity of any kind any more than I believe that Sidartha Gautama, the Buddha, was. Both historic figures, both teaching ethics in their own way and both having had a massive and beneficial effect on humanity in their lifetimes and ever since.
