Advanced Extraterrestrial Civilizations

Do we really believe we’re alone in the universe? With billions of galaxies and planets out there, it’s becoming harder to claim Earth is the only cradle of life. Supporters of alien civilization theories point to astrobiological statistics, unexplained incidents, military leaks, and pilot testimonies. Skeptics reply: no evidence, no discussion. But is the cosmic silence proof of absence—or just of our ignorance? And maybe someone’s already been here, just without leaving the kind of trace we’re willing to see. Decide how open you are to what remains (for now) unknown.
