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.
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.
