Alien,
Dissing all eye-witness evidence just because they are eye-witnesses is daft. Eye-witness evidence is admissible in places like courts and particularly so if lots of people on lots of occasions saw something! If you are going to say that all the alleged eye-witnesses were wrong, you need to give a better explanation.
Here’s a better explanation for you.
1. You’re attempting a negative proof fallacy. It’s for the claimant to show beyond reasonable doubt that the record is accurate, not for others to prove that it's not.
2. There is no eye-witness evidence. Such records as there are were written decades later, and so merely
reported what eye-witnesses allegedly
said.
3. There aren’t records from lots of eye-witnesses. What there actually is is effectively one record that says, “Fred and all his mates saw a resurrection”. In a court of law various witnesses would be given more credence than just one, but there wouldn’t be more credence given to just one because he said his mates saw it too.
4. In a court the witnesses wouldn’t be allowed to collude.
5. In a court there’d be the opportunity to cross examine in order to help eliminate the risk of bias, mistake, dishonesty etc. None of these things can be tested from the limited account we have.
6. In a court of law there’d be the opportunity to ask what else the witness thought to be true. If he also thought ten other superstitious beliefs to be true then his credulity would be taken into account.
7. In a court expert witnesses could be produced to present evidence about, say, drug-induced coma that would provide alternative explanations for the events that were supposedly witnessed.
And so on.
Are you beginning to see the problem here?
Oh, and we didn’t go round and round before as you suggest. If someone asserts that 2+2=5 and is shown to be wrong, just repeating it doesn’t provide an alternative fact worth considering. The trick would be instead to attempt an argument that
isn’t shown to be logically false.
