There's one (1) piece of non-Christian, reasonably contempareneous evidence for the existence of Christ that stands up under examination (Josephus mentions 'James, the brother of Jesus, who was called Christ') and even there, it's entirely possible that the "who was called Christ" bit is an interpolation.

It's just really interesting to me, and truly wild how strongly the conventional wisdom says that the existence of Jesus is historically attested compared to the actual evidence.
