Every time things get really glum on Earth, which is pretty frequent recently, we get a new wave of “aliens are here”, they’re real, blah, blah, blah; coupled with videos, some of which may not be fake of supposedly mysterious aircraft doing amazing things, and topped off with supposedly serious people talking about their belief or knowledge that aliens are visiting Earth. For some reason the aliens seem most interested in visiting the US as these reports come disproportionately from our country. It is all nonsense. Leaving aside the very difficult physics of interstellar travel, it is hard to imagine why other life forms would travel all this way and not actually contact us. What would be the purpose of this? Why Earth, are we so unique and special? Part of this is our wanting to feel like we are special in some way; part of it is reflects a hope that there is some external force, some external group that is going to save us from our self-destructive behaviors. We aren’t and there isn’t.
The most obvious explanation for the unusual aerial phenomenon that are alleged to be observed is that the US has in development a variety of advanced aircraft, which it keeps extremely secret, we always do. We have a lot satellites and telescopes monitoring space; if an interstellar aircraft came, we would undoubtedly see it or detect it. So probably best to ignore the nonsense and focus on how we can stop wars and conflicts among humans that are wasting immense resources that could be used to making humans an interplanetary and interstellar species.
