Christians, can you disprove that Jesus is a fictional character based primarily on the life of Apollonius of Tyana?

No they can't, the facts clearly show that Jesus never exitsed.

The 11 Apostles who died defending their testimony of Christ would not have died defending something they knew was a lie. No serious scholar would deny the existence of Christ. --->"3 For what I received I passed on to you as of first importance[a]: that Christ died for our sins according to the Scriptures, 4 that he was buried, that he was raised on the third day according to the Scriptures, 5 and that he appeared to Cephas,[b] and then to the Twelve. 6 After that, he appeared to more than five hundred of the brothers and sisters at the same time, most of whom are still living, though some have fallen asleep. 7 Then he appeared to James, then to all the apostles, 8 and last of all he appeared to me also, as to one abnormally born." (1 Corinthians 15:3-8)

Christers routinely whack themselves in the forehead with their cult prescribed ball peen hammers. This constant whacking keeps their brains in such a sad state of disrepair that it's impossible for them to function even at very minimal levels without the constant assistance of their cult handlers.

Rolls eyes

Jesus was real but god never existed.

the reality of the Spirit is something you just cant understand lol .. those that are saved are those it is given to .. your external proofs are fallible in any application and can be applied pretty much any way an individual wants to interpret it .. thats not truth ..

What proof do you have that Apollonius existed?

Blind faith.

They believe because they've been indoctrinated to believe, with the not-so-subtle threat of eternal torture if they don't Absolutely believe in Everything their church overlords tell them to believe in.

This is why they resort to threats of hell so quickly. It's what They're afraid of, so they think their fairytales will scare other people too.
