One fascinating angle to consider when pondering why aliens cannot see us and we cannot see them is the possibility of civilizations possessing technology so advanced that they deliberately remain undetectable—what some might call a "super advanced" state. From personal reflections, it seems plausible that these civilizations might use technologies or methods to cloak themselves or avoid any form of communication that could reveal their location. This ties into the Fermi Paradox, which highlights the contradiction between high probabilities of extraterrestrial life and the lack of evidence for it. In my view, prehistoric human societies had no concept of such advanced technologies or the vastness of the universe, which today fuels our curiosity and search through scientific means like SETI (Search for Extraterrestrial Intelligence). The universe’s enormity alone poses great challenges in detection; signals might be too faint, focused elsewhere, or in forms we cannot yet comprehend. Moreover, it's worth considering that extraterrestrial beings might exist outside our current understanding of physics or communication, perhaps utilizing dimensions or energy forms that are invisible to us. This could be why we neither observe them nor have evidence they are observing us. Alternatively, their civilizations may be in a phase contributing to or avoiding interstellar visibility—the so-called "pointing a super advanced" technology might mean they actively choose to stay hidden to prevent cultural contamination or conflict. Sharing this perspective from a user experience point of view, the belief that aliens are watching or that the universe is teeming with unseen life forms impacts how we engage with space exploration and scientific discovery. It encourages humility and patience as humanity develops more advanced technology and knowledge to better detect and understand potential extraterrestrial life.
