Almost all of the Christian folklore surrounding Jesus can be directly tied to other myths that were common knowledge to Mediterranean people at the time.
There was a dude called Jesus, there were a lot of them. That one was Jewish and belonged to an evangelical cult was likely. But we can’t really say that because the Bible exists so too must have the Jesus described within.
What we have today was written by people hundreds of years after the fact. There was nothing written during these events, nothing at least that survived.
If you go looking for proof of Jesus, you’ll either come out disappointed, or delusional. Think of guys like Ken Ham.
Keep the faith, by all means. But part of believing is accepting that you don’t get to have proof.
