With thousands of sightings around the world each year is it possible some of these objects are not from this planet?
With these answers generally falling into quite earthly categories - strange cloud formations, geological events, meteors, as yet unclassified aircraft, misinterpretation of known technology - is there room for the extraterrestrial vehicle explanation?
What are your thoughts?
If at least some UFOs are not of our world, what are they... extraterrestrial vehicles or something else?
If you have a UFO experience that leaves you in no doubt that it was not of this planet please share that too!
