Im not going to argue here, if UFOs are real or not. But recently I realized that IF the observations of UFOs are real, this is a really positive thing. Why? Because if UFOs are real, there is high probability, that these devices are constructed by civilisation which has capability of interstellar travel, meaning that such civilisation is technologically far superior to human civilisation. In other words if we are being observed by advanced civilisation, which could wipe humans as easily as we kill cockroaches, it is very positive, that there was no such extinction event caused by hostile advanced civilisation.
