Finding the patterns is not easy

There do appear to be some hotspots around the world, mainly near nuclear facilities and such-like, but it is unknown as to whether it is coincidental or otherwise. There are cases in India and China and many other places elsewhere. In India there was a recent case where the UFO's were said to be hanging around a nuclear facility there. In China, they get cases too, but getting information out of that country is a bit difficult, but allegedly the government there is as intensely interested in the subject as the US govt is, as is the Russian govt. The responses from each govt can be quite different however. The quality of imagery we get these days is relatively new.. perhaps we will get a few surprises with the cameras you mention. One of the guys at the centre of the interest in the last few years is David Grusch, and he's not just some guy off the street. He and his boss at the time both did have access to what would be good quality imagery from satellites, but as soon as they started poking around the subject they were subject to bullying from above or wherever and losing their jobs etc. They want to reveal what they know, but the secrecy laws in the USA are labyrinthine and have harsh penalties. They both come across as being very intelligent.. just Google them. https://en.wikipedia.org/wiki/David_Grusch_UFO_whistleblower_claims I don't think it is necessarily likely that aliens would want to be in communication with us humans, unless you believe the theories where they already have communicated with political and military leaders. Electromagnetic waves might be too primitive for their liking anyway. If they came from interstellar distances then that would indicate a much greater understanding of matter and energy than we humans have at this time. Some theories say that they are resident on this planet already, have been for millennia or millions of years, but they may have no particular reason to interact with us and can we converse with them in a common language anyway?. Humans are but one species on planet Earth, these aliens or guardians may have the job of protecting all the rest of life from us, the best hunters on the planet for many millions of years. We are, after all, in the middle of what some scientists describe as the Sixth Extinction. Getting rid of us humans would solve that. Earth might just be a zoo, or a big experiment, perhaps a nostalgic recreation of early life on some other planet from billions of years ago.
