Nope, it is what is written in the material itself and the timeline for the collection of works , gospels, Paul's letters, etc, that paints a picture of history....incomplete as it is.
Nope. There is ancient evidence for Jesus from non-Christian sources; sources that Ehrman and thousands of other biblical scholars and historians put stock in. He refers to these sources in his book about the historicity of Jesus. And the non-Christian historical evidence for the existence of Jesus is considered by them to be excellent…even by scholars and historians who are agnostic/atheists. But you “choose to believe” otherwise about the historical record.
But that’s OK; it’s OK with me that you choose to believe whatever you choose to believe.
