Who it be?

98% chance there is no other sentient life within 100-150 light years of Earth. All this alien stuff is a scam by the government to distract us from whatever their next agendas are.

If our government has these capabilities we are safe. If it is China or Russia we are in trouble. I would speculate it is not China or Russia or we would not be pushing our luck in various hot spots around the world, especially Ukraine. If it is aliens we really need to initiate some kind of contact. Since these vehicles, illusions or whatever seem to know our military intimately it could be us. 100 to 150 light years is just a walk in the park. If aliens can travel one light year they most likely can travel thousands or even more. Maybe we Earthlings are just super interesting. By we I mean from the first multi cellular life all the way to the present day. We could be the case study of a savage planet.

No evidence things like warp drive or electrogravitics can actually exist to facilitate faster than light travel.
