If you can say you know the evidence is insufficient, then to be fair, allow others the same privilege. Or if you want to say that others' conclusions are "still an act of belief," then so are yours.
Otherwise, you're making incredibly egotistical posts telling others that they only believe what the evidence indicates, but you alone actually know. What offensive nonsense. We're all competent adults here, forming our own conclusions about the strength of the evidence. Some will say ghostly encounters are evidence of an afterlife; others will say that's weak evidence or none. Some will say that consciousness requiring a brain is evidence that consciousness can't continue immaterially; others will say that's weak evidence or none.
I'd be happy either to say I know or I believe what the strength of the evidence is. What I'm not happy about is being told that you know, but others don't.
