Did Jesus exist?

[athrock]

-and not a single possibility speaks to the historicity of jesus.  No one disputes that christians existed, historically.

Of course not. Nor does anyone dispute where they came from or who they were disciples of:

“Therefore, to put down the rumor, Nero substituted as culprits and punished in the most unusual ways those hated for their shameful acts [flagitia], whom the crowd called 'Chrestians.' The founder of this name, Christ, had been executed in the reign of Tiberius by the procurator Pontius Pilate. Suppressed for a time, the deadly superstition erupted again not only in Judea, the origin of this evil, but also in the city [Rome], where all things horrible and shameful from everywhere come together and become popular. Therefore, first those who admitted to it were arrested, then on their information a very large multitude was convicted, not so much for the crime of arson as for hatred of the human race. Derision was added to their end: they were covered with the skins of wild animals and torn to death by dogs; or they were crucified and when the day ended they were burned as torches. Nero provided his gardens for the spectacle and gave a show in his circus, mixing with the people in charioteer's clothing, or standing on his racing chariot.” (Annals of Imperial Rome 15:44)

The "Chrestianos" were people who followed "Christ" who was executed by the procurator Pontius Pilate.
