Christianity is based on historical events. Throughout the Bible, there were eyewitnesses to events, and those people reported what happened. The Gospels, in particular, have extra-Biblical sources which help confirm their accuracy. First century non-Christian historians who refer to events in the Gospels include Josephus, Pliny the Younger, Suetonius, Tacitus, Thallus, and Emperor Trajan.
