Can UFO's appear anywhere any time?

Answer 1

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.
