I begin to see. Evidently we are too disparate to effectively communicate. My original post meant, to me, 'If you folks seem to think this to be so childish and funny, then it should be no big deal for you to explain every facet of these phenomena.' I guess you took it as 'In the absence of demonstrable proof of the technique involved, I positively assert that aliens did it.'
It is really no great skin off my nose, either way. I happen to believe there are many things we can not explain, and that I am perfectly free to believe about them as I wish, lacking any definitive scientific data/analysis. I do not, however, insist that everyone else believe similarly.
(I ain't real serious about too many things, Haj...;^)
