Can you please point me to the terrestrial explanation for the recent spate of "snake-like" UFO sightings? In the absence of any positive evidence for its existence, I don't believe there is extra-terrestrial life. But I haven't seen any logical explanation for some of the widely observed phenomena, either. I usually assume it involves secret government projects.
