It is a historical event. Jesus was a real person, and there are a lot of sources - outside the bible - about him as a person and his crucifixion.
That's my entire point. I'd like to know the truth behind the religion. I find it absolutely fascinating how historical events get warped over time to become a religion that billions of people still believe in today.
Sadly there are not a lot of extra-biblical sources on Jesus and his life actually.
There is one, a single one. And it’s pretty bad. Josephus. He basically mentions “James, the brother of Jesus they call Christ”, in the middle of a text not about Jesus at all.
I'm not a historian, but Tacitus definitely mentioned Jesus' crucifixion. Saying there are a "a lot" of source is an exaggeration, you're right about that, but there's basically no doubt that Jesus was a real, historical figure. (I'm not saying that you're disputing that, I'm just still stuck on the guy actually thinking that Jesus wasn't real.)
Obviously Christian sources can't be taken at face value, but there's enough corroborating evidence - be it archaeological or written - that proves that at least some of the things in the gospels are based on facts, even if it's certainly embellished and a lot of it likely just made up and/or warped over time.
The Annals of Tacitus were lost throughout history and many of the passages (including the ones that mention Christ) were rewritten in the 11th century by Christian monks. We cannot trust it as an historical source any more than we can trust the Bible itself
I guess then you’d see more if you could witness Paul’s … event. But then again there’s probably no single historical event that explains Christianity. Maybe the 2nd council?
