I don't trust any of the information regarding the character Jesus to be reliable. But that doesnt mean there wasn't a Jesus. I think it is folly to attempt to disprove his existence. At best any can do is expose information that suggests he was only a fictional character.
But that doesn't prove there wasn't a Jesus. Only that the stories were not entirely true.
It is folly as you can't prove a negative. Here is a collection of "historical" but nobody Jesuses to illustrate what I mean by that:
1) In the time of Pontius Pilate some crazy ran into the Temple trashing the place and screaming "I am Jesus, King of the Jews" before some guard ran him through with a sword. Right place right time...and that is it. No preaching, no followers, no crucifixion, nothing but some nut doing the 1st century equivalent of suicide by cop.
2) Paul's teachings ala John Frum inspired others to take up the name "Jesus" and preach their spin on Paul's visions with one of them getting crucified by the Romans by his troubles whose teachings are time shifted so he is before Paul. (John Robertson actually came up with a variant of this in 1900 with this Jesus being inspired by Paul's writings rather then teachings)
3) You could have a Jesus who was born c 12 BCE in the small town of Cana, who preached a few words of Jewish wisdom to small crowds of no more than 10 people at a time, and died due to being run over by a chariot at the age of 50.
You can't prove any of these aren't the "real" Jesus. The real problem is the same one David Kusche presented for the supposed myth of the Bermuda Triangle:
"Say I claim that a parrot has been kidnapped to teach aliens human language and I challenge you to prove that is not true. You can even use Einstein's Theory of Relativity if you like.
There is simply no way to prove such a claim untrue. The burden of proof should be on the people who make these statements, to show where they got their information from, to see if their conclusions and interpretations are valid and if they have left anything out."
The rationalwioi article
Evidence for the historical existence of Jesus Christ looks at the "proof" and it is in really bad shape. Either something is unprovable (ad hoc) or when we
can cross reference it it doesn't match with other records.
I see. So unless your face appeared on a coin or a statue was made of you, you didn't exist? I now totally understand why people say Jesus is a myth.
Writings are the same as books, so they don't count as physical evidence - unless they are on a coin. Writings can be forged or made up, unlike coins and statues which always depict real people.
Always? No. There are plenty of statues or Greek and Roman gods and unless you buy into Euhemerus's expansion of Herodotus' idea of myth being distortions of historical evenst. The Mercury dime is an example of a coin that depicted a person who never existed. This is an unrealistic expectation of history.
This and similar views are the result of misunderstanding the historical method. To grossly oversimplify:
All other things being equal, the closer a piece of evidence is to an event the more it is valued. These approach yields these descending levels of evidence:
1) Contemporary evidence: Material that dates to the time the person or event actually happened - such as documents, media coverage, or eyewitness accounts.
2) Derivative evidence: Material that incorporates or relies on contemporary evidence that has since been lost, such as accounts of events written in ancient times.
3) Comparative evidence: Material that gives details that can be checked against known phenomena of the time.
Historians evaluate this evidence in two primary ways:
Source criticism: This entails determining the reliability of a given source, procedures regarding contradictory evidence, and quality of possible eyewitness evidenceincluding indirect witnesses and oral tradition. Historical Anthropology tries to take this to the next level by looking at cultural dynamics that could influence what events are recored as well of how they are reported though being formed in the 1960s the field is quite young.
Synthesis: historical reasoning - This entails argument for superior explanations (that is, determining which theories are more likely to explain a given bit of evidence?) sometimes using statistical inference and/or argument by analogy.
