People have seen "something", and since physical evidence is seemingly very lacking, it very well could be meta-physical, i.e inter-dimensional, etc. Physicists say there are ten, maybe 11 Dimensions, only four which can be known. Who's to say? Just saying, I like to stay open minded. I will say, if I "saw" one, I would not haul-off and shoot it unless I was threatened. Since I am always "edgy" in bear country (not afraid mind you, just edgy! ha) I am always set on "go", ha. What an adventure this short life is!
