<”And the stories offer similar proofs”>
And the stories were all deception...amid drugs and vivid imaginations.
There are many evidences of spirit, if not proofs in the modern scientific sense. Spirit is willful and it is not amenable to things like being poured out of a flask or heated over a Bunsen burner. So there is no such thing as a “modern scientific experiment” upon spirit. However spirit DOES get involved in relationships as well as in filling (for good or for evil).
