The most obvious evidence is a body that has been missing for 2000 years belonging to a famous historical person that most biblical scholars believe was crucified in Jerusalem on the orders of Pontius Pilate.
From Wiki on the historical Jesus
The majority of biblical scholars who study Early Christianity believe that the Gospels do contain some reliable information about Jesus,[7][8][9] agreeing that Jesus was a Jew who was regarded as a teacher and healer, that he was baptized by John the Baptist, and was crucified in Jerusalem on the orders of the Roman Prefect of Judaea, Pontius Pilate, on the charge of sedition against the Roman Empire.[10][11][12][13][14][15][16][17][18][19][20]

When you claim someone was resurrected, the fact that the body is missing is some evidence, it is not proof, but it is some evidence. Even the Jews wrote hundreds of years later they believe the body was stolen. What does this tell us. It tells us the Jews believed Jesus existed and they believe the tomb was empty. But the Jews have not presented any evidence the body was stolen.
Evidence (not proof) for the Resurrection of this historical person named Jesus (that the majority of biblical scholars believed existed and was crucified on the orders of Pontius Pilate) has been given:

The very first post of Part 1 of this thread gave some evidence that the NT writers told the truth. That post could have been written better by myself. It would probably be better to read Chapter 11 of the book cited in post #1 as it is much more complete. Here it is:

Bottom line is there is much evidence the NT writers told the truth. It is not absolute proof but it is clearly evidence.
