क्या हम पहली सभ्यता हैं या अरबों वर्षों पुरानी किसी उन्नत प्रजाति से पीछे हैं?

Are we truly alone in this vast universe? This question has fascinated humanity for centuries. In 1961, astronomer Frank Drake proposed a mathematical formula known today as the "Drake Equation." Its purpose was to estimate how many intelligent and technologically advanced civilizations might exist in our galaxy. In this video, we'll explain the Drake Equation in simple terms, learn how scientists estimate the number of aliens, what the Fermi Paradox is, and why, if millions of civilizations exist in the universe, no one has contacted us yet. Are we the only intelligent species in the universe, or is there a civilization somewhere far away looking at the sky just like us? If you love space, science, the universe, alien civilizations, and mysterious scientific theories, this video is for you.
