Physicists today might think this way but for a being a long way in the future ? If you're limiting your thought to mainstream science it will only get you so far imo.
Most UFO sightings can be explained away by reason of optical illusions or other such reason, but some small percentage (many) are not easily explained. The UFO stuff around nuclear facilities is really difficult to explain, when the reporters are serious minded military personnel like Robert Salas ?

Just one example from many ?
Mainstream science is what we have to work with as far as UFO's go. Putting aside the almost incredible unlikelihood that aliens could travel the vast distances involved in tiny spacecraft that are what people report they see, why would they decide to spend 50 years hiding from us apart from abducting the occasional person and not provide us any clear objective evidence of their presence. It is fine to speculate about technologies and intelligences vastly ahead of ours, I just don't believe they would behave the way UFO 'sightings' are reported.
