The object did repeated precise manuevers ( several figure 8s ) in the same place on two occasisions and when it departed, it instantly covered over 25 Km from a dead stop in about 1 second. The etreme fast precision maneuvers in the same place on two occasions indicate some kind of flight control system and that implies some kind of intelligence as opposed to a random earthlight or ball lightning phenomenon. Nothing natural or manmade with a flight control system can go from a dead stop to cover over 25 Km in 1 second. So if it wasn't anything manmade or natural that we know of, it had to be alien ( to us ). Where it came from or what it was exactly, I don't know. My best guess is it was some kind of automated probe.
The rest of skeptics here have just resorted to ridicule and/or personal attacks. As irksome as GeeMack may be, technically, you can't rule out that the whole story is fabricated, or that the stimulus was induced by some shared mental and/or perceptual abberation. And if you go with those explanations, you can rule out every unexplained sighting everyone has ever had or will ever have that doesn't include sufficient empirical scientific proof. Exactly what proof they would need has not been made clear.
