It does seem absurd, with the historicity of Jesus being well established and all. I've checked out their arguments but they seemed like a lot of cherry picking and weren't very compelling. Like multiple cultures reporting flood events is somehow a debunking for them, when at the same time science is proving that a lot of these floods did happen.

It was cool to learn a bit about other Jesus-like figures though. Someone has to keep the atheists turned off I guess.
