>>12951I think that if extraterrestrials wanted to visit an uncivilized and technologically-primitive planet like Earth for whatever reason, they could do so easily without us knowing, and UFO conspiracy theories are more a product of our species, rather than reality. Furthermore, if extraterrestrials could visit Earth without anyone knowing, it must follow that they are good because for technology to advance that far in a society would require the perfection of compassion.
...and if extraterrestrials were present, then the proof would be indisputable by now, given nearly everyone on Earth has a cellphone with a high-quality camera now, yet no troves of pictures are coming in. Lastly, the military can't keep secrets, either. So, in conclusion, there are either no aliens visiting Earth, or there are and we don't need to concern ourselves with it.
