Space is stupendously massive with countless galaxies, each with hundreds of billions of stars and trillions of planets and moons. Statistically, there must be life elsewhere in the cosmos and IMHO most of it is probably microscopic and/or not intelligent/spacefaring.
However, if there are intelligent, spacefaring species out there, and if they have visited us – then the massive scale of the cosmos and the incredible technology, knowledge, and ability needed to traverse it would suggest these beings would possess technology and intelligence as far “above” ours/us as we are “above” the chimpanzee…or the ant…or the bacterium…or the virus…and lately and with each passing day, evidence reveals that some humans seem to be de-evolving and acting more and more like a virus.
Therefore, as we mostly naked, multi-colored, bipedal, primates will often camouflage ourselves with our technology and technique in order to study other life forms upon our planet without revealing ourselves to them…
…it is very possible the extraterrestrials have similar technologies (yet vastly superior to ours) that would easily hide them from our detection. Yes, that would then suggest that all the blurry photographs, videos, books, and eyewitness accounts/interviews over all the years by all the people claiming to have seen/encountered/been abducted by aliens are in fact – 100% pure and total bunk manufactured by charlatans wanting attention and fortune.
Another possibility exists: they have been here in the past and yet may still be here (maybe not them personally but their technology – think: cellular/internet-connected wildlife/trail camera traps/webcams etc that would allow them to remotely study us from the comfort of their home planet) studying us as we study other lifeforms on earth – such as looking at chimps and deer in the forest, ants under a magnifying glass, bacteria under a microscope, or African wildlife visiting a waterhole…
Check out Earthcam for many examples of what I mean: https://www.earthcam.com/events/animalcams/
It is also possible that many randomly selected and/or “of importance” or “special interest” humans have been “tagged” with 100% undetectable with our current technologies tracking devices (no, not injected via anal probes or vaccinations – oh lord people please grow up and just stop it with the TV/hollywood inspired stories and lame conspiracy “theories”) so as to be observed by these extraterrestrial observers in the attempt to study the mundane and unique among our species and learn more about us as we wildlife researchers work to learn more about the natural life movements of wild creatures currently existing with us on our home planet.
Or, they may, in fact, be so far evolutionarily, emotionally, and technologically advanced “above” us that we are only mere curiosities to them…or of no interest at all…
Maybe, due to the destructive, hateful, selfish, natures, and our viral reproduction and expansion without any concern for future generations – maybe our solar system has been put in a physically distanced quarantine zone far from the rest of the galaxy and its populated worlds until we children grow up out of our dangerous malignant infancy, start taking care of our planetary life support system, and coexisting with each other and with all species on this strange water-soaked living rock we call earth.
Another view of our home. Can you find the earth in this image? Yes, we are there, the tiny pale blue dot hanging in space under Saturn’s rings on the lower right.
A close-up view.
That’s here, that’s home, that’s us.
Home from 1 million miles away.
“It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the planet Earth. I didn’t feel like a giant. I felt very, very small.” —Neil Armstrong
