Atmosphere Memes

The ultimate evolutionary showdown! On the left, we've got ancient cyanobacteria - the OG oxygen producers that transformed Earth's atmosphere 2.5 billion years ago. On the right, molecular oxygen's sassy diagram looking all "bond with me, bro." The cyanobacteria literally changed the planet's chemistry and enabled complex life while today's carbon-emitting "gassy bois" are reversing their hard work. Talk about ungrateful descendants! Those little bacterial chains were pumping out oxygen before it was cool, creating the conditions for everything that followed. Meanwhile, modern gases are just trying to turn Earth back into a hot mess. The bacterial ancestors are probably rolling in their microfossils right now.
