There is no historical evidence that Jesus lived, let alone was resurrected. What about the 500 other people thet were supposedly ressurected along with him? Did they ascend into heaven too, or did they die again?

You're mighty confused. There weren't 500 other people who were resurrected with him. There was an appearance of the resurrected Christ to about 500 people.

The Gospels are the main, but not only, historical evidence that Jesus lived. The historical authority of the Gospels has been verified by a slew of scholars who have examined it by applying the same tests that are used to determine the accuracy of any other historical account.
