Dr. Bart Ehrman to the Infidel Guy: “I think it matters what happened in history!” And what is he giving as evidence that people existed? Writings about them. “We have more evidence for Jesus than we do for anyone else from his time period.” (Bart Ehrman)
For the record: Dr. Bart Ehrman is an agnostic historian.
I am surprised the person making this video portrayed Dr Ehrman inside a Catholic or Orthodox church building. He is not found there very often.
