yes it is but some believe that it is not. there have been times when people have proven it but many did not believe.
People have reported sightings of UFOs in France, but there is no proof of their existence.
That information is unknown, there are no reliable sources.
UFOs are by their nature, impossible to prove. If they were proven, they would be identified and would cease to be UFOs.
It is possible that UFOs are alive. As they are unidentified it is possible that they are anything. They could be a strange bird, flying squirrel or bat, or some other unknown living creature.
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.
She acted like her very existence depended on whether a boy called her.Scientists have found no evidence of any existence of life on Mars.Philosophers question the reasons of human existence.
You might want to Google search it. There are reported to be UFOs flying in the air, however, the pictures are usually not clear enough to confirm that it is a UFO. Some of them are caused by reflections of the moonlight or other factors.
Even with all the speculation about aliens and UFOs, there are no records about the existence of space aliens. Sorry.
The existence of the so-called UFOs has not been conclusively confirmed. Therefore, we may be receiving visitors from other planets or moons of our own solar system, from other stars, or we may be receiving no visitors at all.
Some people believe that spaceships from other planets have visited Earth, but no one has ever been able to prove it.
The very existence of UFOs - in the sense of visiting spaceships from other planets - has not been confirmed, so any indication about their length would be mere speculation.
Where humans and alcohol are, UFOs will be.
