Are you sure English is your first language? Your profile lists you as "Location: U.S.A." but your ability to comprehend what is being told to you (by more than just myself) seems to be very limited. Do you normally need to take medications for a psychological condition? Have you changed meds if the answer to the previous question is yes?
Look, "I don't know" is a much more intellectually honest answer than idle speculation. We suffer from a severe lack of data. And as a species, we also suffer from a lot of popular culture delusions and contaminations.
For instance:
- Is the desire to explore innate to intelligence and civlization? It was in our particular case, but is that universal?
- Do civilizations survive long enough to develop the unfathomable technology to conquer interstellar distances? Indications of our own civilization are that the chances are poor, but again, that's a datapoint of one.
- Does a civilization become more noisy in the EM spectrum as they advance? Again, our civilization is actually quiteing our EM broadcasts...
You see, those are intelligent type questions to ask, not attempting to really compare them to ourselves, or what the popular media has made up for entertainment purposes.
If I were to make something up, I'd say they are observing us via a system-wide quarantine, and will finally make themselves known by coming here once a critical mass of skeptics populate the planet, and turn all the woos, cons, fundamentalists, and people who can't seem to express themselves coherently into some sort of fertilizer for their bacon farms... See, very silly!
