Jesus' so-called "resurrection" is not historical, because, no one living at the time bothered to mention it among the many thousands of literate human beings who could have. The Romans did not mention it, neither did the Jews, nor the many thousands of pagans. It was not until significantly later that the belief arose, first, as a "spiritual" resurrection that was only visible to believers, and later on, as the belief evolved and morphed over time, to a physical resurrection. With the earliest accounts of Paul being phantasmal to the later of accounts of the Gospel of John (and, still later, the Gospel of Peter) being physical, the resurrection accounts become more "literal" over time.
These accounts are the stuff of legend, not history.
