I believe Jesus probably existed.
I also believe that for someone that is supposed to be the son of god / god , he didn't really say a lot of helpful things.
I mean, every word he spoke should have been recorded. Why didn't someone ask him about cancer/ malaria/ clean drinking water/ dental hygiene/ electricity/ the best possible diet that lets the average person live a long, healthy life? His message was basically, " don't worry - it will all make sense after you die".
This was an opportunity to really lift the everyday existence of the average human. Its only now , 2000 years later that humans have been able to figure all this stuff out on our own, at the cost of millions of lives.
