I haven’t really heard that Jesus of Nazareth didn’t exist as an argument against Christianity, just that he wasn’t God and didn’t to miracles/resurrection.

I’ve seen quite a few folks float the full blown “Jesus was invented by the Romans to trick the occupied state of Palestine into accepting Roman rule” theory.

Apply that to literally every story, think of the motivations behind those writing it, and you can get an amazing moral teacher becoming God.

Sure. Siddhartha (the Buddha), Mohammad, even Confucius to come extent.

But like with most of these, the divinity of a figure is decided on well after they’ve been dead and buried. What I’m stuck on in the denialist “You can’t prove Ancient Historical Figure X existed now that I’ve arbitrarily rejected the veracity of all the existing materials.”

But to the point of the meme, from the perspective of people in the future, there may have been a Peter Parker, but there’s no reason to believe there was a Spider-man

The point of the meme is that religious texts are fictional, because fictional texts exist.

The point of the religion is that society should organize itself around certain traditions and taboos, because it will lead to a utopian future of peace and plenty.

There difference between Jesus and Spider-Man isn’t their magical powers, its their activist base of enthusiastic followers.
