Are humans alone in the universe?

Do you think we’re alone in the universe? In this video, I head out into a quiet forest and start with a simple question about being alone… but it quickly turns into something much bigger. Using a few rough calculations, some basic science, and a lot of thinking time, I explore whether intelligent alien life could actually exist anywhere else in our galaxy. Rather than focusing on famous ideas like the Drake Equation or the Fermi Paradox, this video looks at something more fundamental — how life began on Earth, and how a single, incredibly unlikely event may have led to complex life as we know it. From early chemistry and amino acids, to RNA, proteins, and the first cell-like structures… right through to the moment when two cells stayed together instead of drifting apart — the origin of all animals — this video breaks down the science in a simple, easy-to-follow way. And the conclusion? That we might not just be rare… we might be completely alone in the Milky Way. Of course, this is just one perspective — so I’d really like to hear what you think. Do you believe intelligent life exists elsewhere? Or are we the only ones? Let me know in the comments. ________________________________________ 📌 Topics covered: • Are we alone in the universe? • Intelligent alien life vs simple life • The origin of life on Earth • RNA, proteins, and early cells explained simply • Multicellular life and evolution • The Great Filter theory • Why complex life might be incredibly rare
