This was a tangent from another thread in which we were debating faith and science... PSacramento (thx) rightly pointed out that I was digressing so here' s a new thread.
IMO, it all comes down to (religious) people trying to pin an ABSOLUTE answer on an unexplained event. (ie, the first cause = creation by Judeo-Christian god, holy spirit coming upon someone, or a demon experience...)
The superstitious and/or religious will quickly attribute the unexplained to a spirit being(s).
Science will search for the answers but if none bear evidence, the unexplained simply remains unexplained... until a theory passes through the scientific method meat grinder and comes out the other side intact.
The scientific method is well-established and documented. What consistent method of reasoning and testing is used by the vast majority of the religious community to show how they arrive at their conclusions (doctrine)?
