Consciousness creates materiality...

First hand accounts (anecdotal evidence) are ok for criminal investigations (if that's what you're referring to) but things like DNA and fingerprints evidence (scientific/objective data) are far preferable as witnesses are often prone to making mistakes (or even flat out lying). But even then that isn't really comparable to first accounts of the supernatural, we know people get murdered/robbed/etc (there's plenty of video footage of that ), it's been known to happen so there's actual plausibility on murder and robbery claims, there's no solid concrete evidence for the supernatural/metaphysical/etc so the plausibility of such claims is no where no near comparable. It's why "I saw that person get murdered" is far more believable than "I saw that person vanish into thin air". One is far more plausible than the other.
