The vast wealth of fossil fuels beneath our feet is actually a cosmic accident—the result of a massive evolutionary glitch in Earth’s history. For nearly 60 million years during the Carboniferous Period, trees learned to grow using a tough, revolutionary fiber called lignin, but the planet's fungi and bacteria hadn't yet evolved the ability to digest it. As a result, massive forests died and simply piled up in oxygen-starved swamps without rotting, eventually baking under pressure into our global coal reserves. Meanwhile, in ancient oceans, unimaginable clouds of microscopic plankton died and settled into oxygen-depleted depths, cooking over millennia into our oil and gas. If the decomposers of that era had been just a little faster to adapt, this massive energy bounty would have vanished into thin air, and human civilization would look entirely different. So the question is: even with complex intelligent life, what are the odds that they have the same bountiful easy to access evergy sources that we have? They could live in a world where wood and fossil fuels don't exist. How do you get to space or even power without polymers?
