The big question is whether spirits actually exist. The extremes in thinking on this subject are either that it is complete hogwash or that there are ghosts and spirits all over the place. The truth is probably someplace in the middle. A very large percentage of the World's population believe that there is some sort of spiritual sense in people that is beyond the physical body and mind. Many of those people believe in some sort of formalized religion with a Supreme Being or God.
Most people believe that everyone has a soul or that there is some universal soul or spirit.
Some believe that animals also have spirits. These souls or spirits are thought to exist after the body dies. Views of scientists Many scientists do not believe in any sort of spiritual experiences. They believe that if something cannot be proved and verified with repeated experiments, then it must be false. Since the 6th sense seems so unpredictable, they feel that is must be just coincidence.
