So an atheist friend of mine is attempting to refute Fátima
First step: if he’s trying to refute something, ask him to explain what exactly he is trying to refute and why. Atheists attacking strawmen aren’t exactly unheard of.
saying that since not everyone saw the same thing and everyone expected something to happen that there is evidence of wishful thinking which caused people to experience something much like hypnosis on a stage.
Then he is free to try to reproduce the same experience. Shouldn’t be too hard, if he’s right.
Of course, it is not just that he has no evidence showing that this is what happened, he also has no way to reproduce it (even using technology unavailable at that time), nor any explanation of how it could be reproduced.
And if this experience can’t be reproduced so easily (or even at all) - is there some reason why we shouldn’t think it to be miraculous?
Which is why you should ask what exactly he is trying to refute. As I said, atheists attacking strawmen aren’t exactly unheard of. And this one seems to be attacking a strawman “The Sun physically moved for this miracle.”.
But no one claims that. The claim is that the Sun
appeared to move.
How do I even begin to refute this since we have no accounts from anywhere outside Fátima, no video of the event, and no pictures showing anything bizarre in photos?
That’s a wrong question. Why should you present any evidence at all at this point? Did he show any ability to use the evidence he already has?
If you show too much eagerness in presenting the evidence, you will only reinforce the impression that the atheist is some sort of a “judge”, impartial and honest by definition, who only has to rule on evidence that is given him without any effort on his part.
But that impression is completely wrong. It is his job to investigate, not your job. And he doesn’t get to just assume he’s perfectly impartial and honest - he should make an effort to be impartial and honest.
And thus at some point it might be a good idea to ask him if he thinks he’s impartial and honest - and why. What precautions has he taken to stay impartial and honest? Just know in advance that he isn’t going to like this question, as he is, um, unlikely to have good answers.
For now, you might wish to ask him where did he look for the evidence, and what evidence would he expect to find if Catholic claim was true. And why.
