UFO means "Unidentified Flying Object". If it is in the sky, and you yourself do not know what it is, then to you it is a UFO. The problem is that people seem to think that UFO is an acronym for Alien Spacecraft, which it isn't. In fact, neither aliens or spacecraft are actually known and proven to exist. It is at best foolishness, and at worst scamming, for the media to pretend otherwise.
There is photographic and video evidence, as well as radar readings and eyewitness testimonies (Eyewitness testimonies are not evidence, but are noteworthy); however there is no evidence as to what the unexplainable ones are or their origins.
There is no evidence that proves any of them are even extraterrestrial for certain. There is no Evidence that proves any of them are not extraterrestrial for certain.
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.
There is no credible evidence for this.
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 are none in existence. You can only find images that people claim to be aliens or UFOs. So far, there has never been any evidence to support their claims.
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.
There is no confirmed evidence in favour of this.
Not very good I'm afraid. In all the decades that UFOs have been sighted or reported, no credible evidence has been put forward that UFOs are from anywhere but the planet earth, either produced by human hands or by human imaginations. None whatsoever.
There is limited solid evidence of any kind in the bible, certainly none of aliens. However, there are certain events recorded in the Bible that could be interpreted as describing UFOs and/or aliens.
Evidence is lacking as to whether unidentified flying objects originate from Mars. No answer as to the nature and origin of UFOs has been found in the course of any of the space probes or manned space flights thus far. Neither has an answer to the question of the point of origin of UFOs been found among any of the information gathered by the space station or by any of the earth-orbiting satellites.

Personally, I ponder dubiously evidence of UFOs.
