UFOs: How do you account for them?

Is God’s focus on the earth, or is the earth one of several or many foci? This is quite an interesting issue, so your comments are appreciated. You can address any or all of the following: (1) Do sane [and sober] people actually see UFO’s that are beyond naturalistic explanation (not military projects, cloud formations, asteroids, etc.). (2) If so, are these connected to the demonic? (3) Do you see a connection to the Nephilim of Genesis 6?
