Yes, UFO's exist river, please read my previous reply......And so...which leads to the reality of UFO's and their actual existence .
UFOlogy in reality has simply developed into a mythical and cultural phenomenon, where all natural, meteorological and astronomical possibilities are ignored, or summarily dismissed after investigation by the converted and faithful.
UFO's and UFOologists are rightly portrayed as a silly pop-culture obsession, which is evidenced by the religious and church like gatherings at their regular Paranormal Pub meetings.
The ironic thing about the closeted and not so closeted claims of the impressionables in this thread, is the fact that the critics and cynics of these Alien visitation claims, on this thread, plus most scientists, particularly astronomers and cosmologists, and myself, certainly believe we are not alone in this universe, and just as obviously would dearly desire that the proper scientific evidence and/or actual contact with Aliens, actually happen before too many of us kick the bucket.
So the question arises, why do they/we reject the "evidence" for UFO's as lacking any real substance.
In fact a growing number of scientists, are of the opinion, that the extraordinary evidence for ETL will be forthcoming within the next decade or so, as a result of the increasing numbers of extra solar planets being discovered, and more sensitive instruments to detect atmospheric content, signals etc become available.
