UFOs make humans scratch their heads; that is, until they figure out what they're looking at.
Humans are naturally curious and are constantly seeking knowledge. UFO's are fascinating for most people, all over the world.
Yes, when the ufo crashed at roswell pretty much humans carried the bodies out of there
I believe they are hiding a UFO. They are hiding all the UFO's at Area 51. They are hiding them because they do not want to scare anyone. Also, reports have said that humans and aliens are working together! They are hiding that too. But don't be afraid, reports say they are working with humans to protect earth. PS, this information came from the TV show UFO Hunters.

It stands for Unidentified Flying Object. Which means exactly that. It doesn't have to be an alien ship, it means that it has not yet been identified. The are many reported UFO sightings that turn out to be the handiwork of humans.

There is absolutely no way to know. UFO's have been visiting our planet for thousands of years. If science is correct, our brothers that lived in caves would have been the first humans to see aliens or UFOs.
If such a thing as "UFO's" exist, they would certainly have the ability to do as they wish. Any restraint that they might exercise would no doubt be their effort to minimize panic among the "simplistic" life forms on this planet. IF they exist, that is. Answer: I believe UFO's could appear anywhere and anytime. I think most sightings of UFO's occur at night. I think space aliens prefer to visit Earth at night because fewer humans will see them. Maybe the aliens are concerned for the humans safety, because crop circles, allegedly made by UFO's, flatten crops, and some dead farm animals (although often unusually mutilated suggesting actual possible physical contact with aliens), have been found laying in farmer's fields, suggesting they may have been killed by radiation, heat, light, fear, or whatever, resulting from a UFO coming close to them. Maybe the aliens fear if they get too close to humans, that humans could die or get sick from the UFO's radiation or whatever. Maybe UFO's prefer to visit Earth at night because they're on surveillance missions and don't want to attract attention.
