Hi Lam, Jesus was mentioned in various non source documents such as Tacitus and Erasmus. The shroud of Turin although partially debunked still can not be said not to be the acutal shroud. The spear that was said to pierce his side although remanufactured later still contains wood and bits of metal from the time of his life. At a time of brutal rule from Rome there were many many so called revolutionarys such as Jesus, his story caught on and spred throughout the region and eventually became the dominating belief in Europe for thousands of years. It stands to reason he must of been an extrodinary person.
There seems to be more evidence for Jesus than Socrates. I am aware that some of the non source mention of Jesus was redacted or added. But the writings of Mark (the earliest writings) does mention Jesus, albeit many years post his death. But is all this evidence? That depends on ones interpretation and ones standards of what constitutes evidence. I personally believe that this man did live and die most likely how was described. Was he God? Is the better question.
