Firstly, I don't think anyone is trying to shut down something because it doesn't seem possible. People are making very bold claims, going on shows with millions of views, and telling people that they've seen things which defy the known laws, things which are totally incredible, without providing any evidence. Therefore it should be expected that people immediately cast doubt - because that's the right thing to do.
The moment people turn up and start making incredible claims, and people just 'accept' by default that they're telling the truth and we don't ask for evidence, or ask serious questions and scrutinise - it sets a very dangerous precedence, because people start believing in any old nonsense.
But this is the big pitfall, just because we can't prove or disprove to a degree of 100% whether something is true or false, somehow means that there's an almost equal possibility of it actually being true, therefore we mustn't rule it out, because we can't prove it's false.
In actual fact, you don't need to prove it as being false to say that it's astronomically unlikely to be true - because that's the truth, it's so unlikely, that it practically can be ruled out, it doesn't have to be proven to be false. We do however, have to reserve in the back of the mind, a place where in future - a wider range of evidence may come in that makes it far more possible, but only until that happens.
EG; Despite the sketchy reports from all over the place, that faith healing works, I don't have to waste time proving that it doesn't work, I just rule it out by default - because it's nonsense, and that's all that needs to be said.
