In 1950, physicist Enrico Fermi famously asked, 'Where is everybody?' In such a vast universe, how could life exist only on Earth? This existential query has fueled decades of debate, conjuring visions of alien worlds. Soon, a scientific quest to find beings beyond our own was established: SETI, the Search for Extraterrestrial Intelligence. Though initially targeting nearby planets, tools like the Kepler Space Telescope now probe distant exoplanets, searching for biosignatures like oxygen that could indicate life. But are our technologies too primitive to detect extraterrestrial organisms? Or might our loneliness be intentional, advanced aliens withholding contact? Or could life itself be rarer than presumed? Despite countless theories, most scientists agree that Earth is unlikely the sole cradle of life. With technological advancements, could we soon answer Fermi's profound question?
