I guess the strongest evidence for not believing in UFOs would be that they haven't landed and introduced themselves. For some people to believe they would have to see the beings.
It would be reasonable to assume that they don't, given that the evidence for actual UFOs are, to put it mildly, lacking. Although the absence of evidence is not the evidence of absence, the only rational conclusion we can draw is that UFOs don't exist, and thus could not directly affect a community.
There is no credible evidence for this.
The instant they are found they cease to exist. They are found and then they are identified. Once identified they cease to be UFOs.
no one knows, its the samething with big foot or werewolves. there is no evidence that they exist or that they dont exist.
No. There is no evidence to suggest that NASA has done this. No other country has any well-documented evidence of UFOs. It is very unlikely that NASA has been able to control the evidence in all other countries.
It is impossible to even speculate. There is no admitted proof that UFOs do exist and no hard information on propulsion.
There is no confirmed evidence in favour of this.
Extraterrestrial life forms-if they exist.
