Phantasm I love you, but you puzzle me. None of the footage you've posted so far is any evidence of ETs. UFOs sure, but that's a loaded word.
As I recall, very poorly I'm afraid, there was a some famous UFO footage exposed perhaps 10 years about by a Vancouver, BC satellite operator who piggybacked on one of nasa's shuttle's signal uploads to earth. The video he obtained showed the shuttle in orbit around earth, with what looked like an armada of perhaps a dozen white point-like objects in the background. Once zoomed onto, some of these objects ceased to look point-like, but were instead roughly hexagonal, greyish-white, with a hole in their center. This was the coolest footage I've ever seen about potential ETs, however, they never strayed from their straight line paths and exhibited no movements beyond their present inertia. Life is not inertial. It changes paths on a whim and is not entirely subject to the environmental physics at hand. It has a choice to curve, even when gravity says keep going straight. Please convince me of ETs. I sure would love to believe.
