The dimension in which we operate with our biological bodies corresponds to a perception of existence obtained by our organs of sensation, our organs of sensation are designed to perceive a limited expression of the vibratory frequency of the surrounding energy, the so-called "physical world" . It is because of this, that we cannot see, hear, touch, smell or taste... those other dimensions, which are simply different expressions of the same existence based on a higher frequency of energy. That said, for the purpose of the "Aliens" thing. The scientific community does not take this path into account," which in my opinion is the most obvious path towards the search for higher forms of intelligent life.<br>But if the search is precisely for biological life forms that operate in the same dimension as us", there are witnesses who claim to have had physical contact with biological life forms not originating from Earth, of all of them the most reliable are those who worked to the governments. And they had the courage to tell their story. You can find them and go down the rabbit hole dear Lex. That said, I return to my miserable human experience, I give full credit to google translate for this comment.
