I would truly like to believe the drones could be something else, like intergalactic forces coming in touch with the decaying human race to bring positive changes, renewing the hopes of a better future, but at the current stage we have reached as society, such beliefs and expectations have also fade out.
Actually that would be the worst case scenario, if those drones had anything to do with aliens. It would translate in such a disruption of society that it would bring negative changes within our culture and politics. even worse if those aliens consider us to be inferior and thus they tried to eliminate us, so they can grab the resources of earth for whatever they may need them.
It would even a better scenario if those drones happened to be sent by the CCP from China and successfully violated the USA air space and the government has become reluctant on taking them down.
The minimal alien possibility would the the wackiest and also the most dangerous one.
Aliens could mean the end through annihilation of human beings or through the enforcement of a more "evolved" law system. What I can say is that the way the world is right now is unbearable already. Anyway, since an early age I've heared about aliens and UFOs, but nothing for sure was ever prooved. So I don't spend my time anymore with these matters, since it's just a mean for charlatans to arise attention to themselves and to make an income from.
