Call me a born skeptic, but I do not believe many of the sightings of UFOs are evidence of alien life.
There have been many theories about what happened at Roswell, USA in the summer of 1947. Many conspiracy theories have emerged. This video may just be another.
What I do think is that there is very likely to be some form of intelligent life elsewhere in the universe, although I am surprised that in over 60 years of looking (via SETI) we have found no evidence.
