Evidence that sometimes we do not have sufficiently into account, is to confront any situation, for example undertake online business, you should be equipped with the necessary weapons to get the achievements that you intend. Subliminal messages are one of them. To understand us’m going to explain with an allegory brought a little hairs, but very graphic: abductions of extraterrestrial beings. It HA! As expected, and you’ll see. The problem of abductions is based on aliens, once accepted as empirical possibility (at least as reasoning), have to be capable of projecting from improbably distant spaces, until what we call our world. Fantastic.
As well, to achieve these skills, they have have developed a few different to our mental and physical mechanisms. Otherwise, we would have already done so. We are good. These conditions involve a far superior to our restricted human capacity development. To make those trips, they will need a few structural supports (body/mind) different to those we know. Their metabolism has clearly differ with what we understand as body material. How but might include sailings from thousands of years light (I don’t have fingers to count)?.
Or hundreds. Or only some tens of billions of kilometers. And its technology must adapt to these conditions. Therefore, its ships must be upgraded to their metabolisms. Humans still communicate by vibrating the vocal cords, giving meaning to those sounds. By very sophisticated to believe than the interpretations of them, they are not more than that, growls, in a hierarchical level higher than other animals. Point. This reduces our humanity, the ability to believe that we are above other beasts. And little else. All our physiological makeup follows the same pattern. To what we were going, if it turns out that the aliens come from distant places, and want to acquire knowledge about other forms of life, they must analyze them.
