And you cherry pick them. I've pointed out a number of details from the gospels that ring false but you ignore them.
Would somebody make up the details of the conversation that Jesus had with Pilate if they weren't there and couldn't possibly know. Yes, they would. That is a detail that rings false. Filling in conversations of which there is no record is exactly the kind of things that the writers of historical fiction and "drama documentaries" do.
Aren't you assuming there was nobody in the room with Pilate and Jesus? We know that someone in Herod's household (and therefore possibly other people in high places)became a Christian. Clearly the conversation between Jesus and Pilate could have been overheard by a guard or someone else, and found its way into the disciples' network.
Regarding the conversation itself, Calvin says about Jesus' reply to Pilate ("you have said so"):
<<But as he did not intend to take pains to vindicate himself, as is usually the case with criminals, the Evangelists put down a doubtful reply; as if they had said, that he did not deny that he was a king, but that he indirectly pointed out the calumny which his enemies unjustly brought against him>>
Does this sound made up?
No attempt to vindicate himself, as we would expect if this was fiction.
The details added by John. Are they the kind of thing that is made up? Wake up jeremy.
