What evidence is there for Alexander? Julius Caesar? Coins, statues? But I'll bet you believe they were real people.None of those people were alive at the supposed time of Jesus and at best were repeating what Christians told them.
No secular historical proof for Jesus. None.
What about Socrates? We have no primary evidence for his existence, either. Do you believe Socrates was a real person?

Evidence for historical figures is extremely hard to come by.
You believe evolution is real because the scientific community mostly agrees on it.
But you don't believe Jesus was real even though the scholarly community overwhelmingly agrees with his existence.
