The case in favor of John grows stronger when we add another internal element: the author of this account was familiar with Palestine.
Some doubt that Jesus ever existed. But they’re in the minority. There’s just too much evidence to the contrary: The first century Roman historian Tacitus (born c. AD 55) mentions Jesus in his Annals (15:44). Tacitus’ Jewish contemporary, Josephus (born c. AD 37), references Jesus twice in his Antiquities of the Jews (18.3.3; 20.9.1). Pliny the Younger (born AD 61), the Roman magistrate, mentions Jesus in his letter to the Emperor Trajan (Letters, vol. 2, 10:96). And the second-century satirist, Lucian of Samosata (born AD 125), speaks of Jesus in his work The Death of Peregrine (11-13).
