Right, but the Bible itself is good evidence, as it was written by real people who wrote about him. Matthew, Mark, Luke, and John were real and knew him, we also have the letters of St. Peter (which were turned into the two books of the Bible). There’s also writings from historians such as Quadratus, Flavius Josephus, Tacitus, Suetonius, Lucian of Samosata, and Thallus. We’ve also found archeological evidence of Roman crucifixions and Nazareth existing.
But also, he was a wandering peasant. How many wandering peasants from 2000+ years ago leave evidence of their existence? He wasn’t important to anyone until after he died. So it makes sense there’s no archeological footprint. You don’t have to be a Christian to agree that yeah, a dude named Jesus who grew up in Nazareth was probably real, and was probably killed by the Roman’s in a crucifixion. But wether he is the son of god, the messiah, or magic healing man is up to you
And yet none of those were written until long after, the four gospels are inconsistent and contradictory, and very little is said beyond speculation or what was already established by early Christians that spread around in the same way we know about Greek/Roman myths. Roman crucifixion at the time contradicts biblical account of it as well. I can quote genetic engineering and SpiderMan comics and the places and events in the comics based on real-world ideas, still doesn’t make him real.
