Think about this: UFO, that is alien spacecrafts for the UFO fans, crash constantly. This show how silly and primitive ETs are, and there is more. Instead of learn from us, humans, they play hide and seek in a perfectly stupid game that not only is not funny but keep them ignorant.These childish entities, (with all due respect to kids that are always more intelligent,) practice abductions and show that their medical technology is primitive and inefficient.Presumably they are here from the beginning of historical times losing their time with their stupid games.
If these aliens are in contact with the authorities, it is evident that humans learned nothing from the "visitors" and vice versa, the unwanted guests learned nothing from us. The mystery here, the amazing miracle is that the UFO industry can keep the myth relatively alive. As the priests do, they profit with some people's need to believe.
