I almost agree with everything Lex said. From my point of view, humanity sometimes tends to be too egocentric and to think that life and the way of communication can exist only on the basis we know. As said in the video, there can be many other variations of life and the way of communicate. Science should be maybe little bit more open to possibilities for which we do not yet have demonstrable evidence. For me, the amazing example is Einstein (and others from the past) and his theories, which proved to be correct a few decades later. And yes Lex these videos about aliens and other civilizations possibilities are very interesting :),(reply>), What are you even talking about? How else would life communicate? There are only so many possibilities for communication? Are you talking about electromagnetic radiation? Like lasers? What other ways could you communicate? Let’s talk science here, not made up fantasy
