I think the greatest argument against that notion is that we do not speak either Mandarin or Russian. And how do they explain the long history of valid UFO sightings, especially those that arose during the WWII years. Where do they think the term "foo fighters" came from? Do they seriously think that if either China or Russia, two countries who really have always hated us, would not exploit technology that is light years ahead of anything else on Earth?
