One Strange Rock: Genesis

Earth gives birth to life. The building blocks of life are common across the universe, but life is rare. What's so special about Earth that it emerged here? Only here on Earth have we found the elixir of life; water in its three forms. But for life to emerge this isn't enough… huge tides created by the proximity of our perfect Moon, plate tectonics, volcanoes and lightning mean the Earth is a dynamic planet. It's a huge planetary chemical experiment, a bubbling cauldron that transforms dead minerals into deoxyribonucleic acid (DNA); the code for all life.
