I think some people believe that life is like a movie, and anything remotely weird they’re unable to explain off-hand is evidence of something extraordinary when it is quite mundane. Some people notice something, word gets out on social media, and then other people start to look at the sky more and notice things. There’s even a word for this phenomenon, it’s called the Baader-Meinhof effect. If I were to create a spy drone, I wouldn’t design it to have navigation lights so that it can be easily seen by people. The first video I saw was without any context and was pretty blurry but even then, I saw that it was very obviously just a drone.
