In history you read about elves, fairies, little people, spirits. It was an accepted part of reality.
But now that’s obvious nonsense and if you see fairies then you need a doctor.
Are we insane now?
Yes I know, nutrition, literacy and the scientific enlightenment. But still.


People used to believe in myths which are unfalsifiable because they wanted to explain things that they didn’t know how they really worked. Now we realise that we should admit when we don’t know something and had scientific methods to try and find out what’s really going on. And no point were we insane, just using normal human psychology.
I think they actually saw the stuff. Myths came after that.
I actually think we might be seeing differently now.
I hear that it was more common to see the little people in times of starvation. And now we don’t starve. So that’s something to consider
