Around 50 A.D., the Jews of Thessalonica accused the disciples of turning the world upside down. That was no more than 20 years after the death and resurrection of Jesus Christ. If these events were not true, the Jews could never have made such accusations, since without any historical validity, their claims would have easily been proven to be false. But, that's not what we find. In similar ways, Tacitus says that people hate Christians (in the 1st century) because of their "enormities", thus proving that the supernatural doctrines concerning Christ did not arise in later centuries. Moreover, the Babylonian Talmud accuses Jesus of practicing sorcery, which proves that he really did miracles. This fits very well with the picture that we find in the New Testament. We find that the plot line in the Bible matches the historical evidence.
