While there are many scholars who have spent lifetimes studying/writing about the historicity of Jesus, they've had very little to work with. The "historical Jesus" that they've constructed is all speculative. The story of Jesus as written about in the Bible, a religious document, is internally inconsistent and in some cases it has not been corroborated by independent 3rd party sources; in other cases it has been proven false. We're all very familiar with this story, but since its historicity has not been established it's more accurate to call the story a myth.
What are these other cases where the Bible has been proven to be false? I've yet to find a single instance where this has actually been so. And no, the Bible does not say that the creative days of Genesis were only 24 hours in length apiece. Creationists wrongly conclude that, not the Bible.
In the case of Josephus, the earliest and probably most cited reference, often given as the "best proof" of a historical Jesus, it has been pretty well established by now that the passage being referenced is a forgery added to Josephus' work after the fact.
The other three references come later. All are brief. There is some dispute over whether or not the Pliny reference is really referring to Jesus or not. They mention the persecution of Christians in passing.
It would be very much the equivalent of me writing down "I traveled to Mecca where I met many Muslims. These Muslims read from the holy book Qu'ran which was dictated by the prophet Muhammad, whom they venerate." - I could write that. It's true. But it's not evidence for there being a historical Muhammad in the 7th century. It's only evidence for there being Muslims today.
The existence of Christians in the Roman Empire by the 1st century is pretty well established. By the 2nd century it's extensively documented. But outside of the Bible the existence of Jesus is not recorded in any surviving text from the time he was alive.
I left a single comment. People responded to it. I responded back.
I thought of a relevant Bible verse for a quiz about the life of Jesus and indeed about our trying to remember things about Him: "Jesus Christ is the same yesterday and today and forever." (Hebrews 13:8)
Wait a minute...
Please could you tell me though, what defines a 'holiday' in the US? Palm Sunday is described as a holiday in this particular quiz and Guy Fawkes night was, in another quiz. In the UK we would probably refer to these as celebrations or festivals, as a holiday for us usually means much of the population gets a day off work.
