Well, this is certainly one of the most “tame” theory, and one that seems the most reasonable.
I leave that here if you’re interested :
Google Prime Directive.
Everyone jumps to the most wonderous conclusion possible when it comes alien life, but this in my opinion is the most plausible likelihood. Humanity is not only a relatively new civilization, but it would also kind of make sense that in the grand scheme of things we aren’t really all that important as a species. We only just reached our own moon less than 100 years ago. I think the idea of humanity being just a mediocre species in the grand scheme of things is scarier thought to some people over the idea that we are of some unique importance.
It would also make sense given that lots of “official” declassified reports of UAP/UFOs tend to focus around nuclear and military testing sites as well as active war zones. Kind of like they are checking to make sure we aren’t annihilating ourselves. I can just imagine an alien civilization laughing over the fact those stupid hairless apes got into another war and being informed in sheer horror that not only did we split the atom, we used it as a weapon against our own kind just to see what would happen instead of using it as an energy source.
I’m pretty sure aliens already visited earth looking for intelligent life abd didn’t find any.
This. This is my favourite take on the whole conundrum.
Capitalism. It leads us to selfdestruct. Therefore, only civilizations that managed to overcome that obstacle managed to reach spaceflight, and they are watching us right now in shock and horror as we dance towards the planetary obliteration fully aware of what we do but unable to stop because few thousands people’s profits are more important than entire species.
Well, it’s as good answer as at least few other Fermi Paradox answers.
