Perhaps the thing I understand least about the supernatural is this gentlemen’s agreement God and the devil seem to have about remaining undetectable by scientific instruments. It seems like one of them could come out of hiding and gain more of a following. I mean, all I see is Prophet Yahweh praying specks into the sky (he rubs me the wrong way for using God’s name as using it that way is something Jews see as disrespecting God). I also read they video taped a spirit that manipulated a candle flame a bit. I lost the link to it though.
