Maybe he existed… but only as a common human and all the supernatural things were added later
Lets consider that jesus did exist and did someone have a cure for leprosy. Why didn't he give that cure to everyone??? We still have leprosy today, kinda proves he didnt have the cure. But again lets say he did and he only gave it to a couple people, not a very godly thing to do, to withhold that cure from the entirety of humanity.
a lot of what he was teaching was for-real insight about life
yaaa cept for the fact that most if not all the things 'jeebus' supposedly said were said in older books already. So there is nothing new in the new testament, they stole all of it from older books like code of hammurabi and then invented a character to say the things.
The new testament is just old testament fan fiction. By that reasoning all these newer religions like Mormonism are fan fiction based on other fan fiction... and Im sure I dont have to tell anyone how loony tunes Mormonism is.
In religions nothing makes sense and thats the entire point. All religions are a basically a gullibility test, and they only want the ones who Fail that test to be in their cult. Its been like this for thousands of years.
My favorite episode of TNG is the one where they encountered Earth, Wind and Fire
