Why Only Earth Has Fire
Season 6
Episode 10
Earth isn’t the only watery planet in the known universe, but it is the only fiery planet. The sun is mostly hydrogen undergoing nuclear fusion, not fire. And on other planets magma from volcanoes and lightning are also not fire. To get fire, it took billions of years of photosynthesis, which means fire can’t exist without life. And fire and life have been shaping each other ever since.
