Of course UFOs are a common sight. The average person can’t identify anything. It doesn’t mean aliens and it never is aliens. There are much more logical explanations than aliens having the technology to get here, the desire to remain undetected, but somehow lacking the ability to not be detected with their super advanced technology. If they can get to us, they could easily have a satalite in empty space somewhere taking super high detailed pictures without having to fly around in the earth’s atmosphere. It makes no sense.
