Schrödinger's cat
Seeing ghosts, visions, belief in the paranormal, belief in the power of prayer ... all these things can be explained as the inevitable result of cognitive biases, fallible perceptions and malleable memories. Our brains are hardwired to look for patterns and assign significance to the ones we think we see, and they are so good at it they will see signals in the noise even where there is only noise. We even know why that is - false positives are not as potentially fatal as false negatives, so these biases have been selected for by evolution. Anyone with the understanding of this we have now could have predicted millennia ago that these sort of beliefs would become widespread, regardless of whether there is any real basis for them.
That's why the scientific method had to be invented, and it has proved to be a highly effective way of determining which of the patterns and signals we think we see really are there. The ones that are attributed to the supernatural/paranormal turn out to be amongst those that aren't really there. Sorry, but there it is.
