Did Jesus exist? Or was He a myth like Santa Claus. It’s a popular comparison.
It’s a comparison Wintery Knight tackles in his post Did Jesus exist? Agnostic historian Bart Ehrman debates Infidel Guy.
In it he says:
When I look at atheists, I do see a lot of belief without evidence, and I suspect that they are just projecting their childish Santa Claus epistemology on Christians.
He also provides a great video debate between Bart Ehrman and Infidel Guy regarding serious historians and the evidence for Jesus, making the Santa Claus comparison silly.
I highly recommend it.
