The term UFO stands for 'Unidentified Flying Object'. So as long as someone in the world has genuinely seen something flying and they don't know what it is, then UFO in their categorical sense are certainly real. However, a forum of essentially rationalist individuals should be in accordance that the evidence for actual alien UFOs is, like many collective, non-academic theories, fragmented and inconclusive to the point of there being no point in believing in them. As always, any evidence to refute anything I surmise is gladly received, with great interest and an open mind.
