Origins-of-life Memes

While people out here thanking their preferred deity for life, the real MVP is a bunch of ancient bacteria that decided to start photosynthesizing about 2.4 billion years ago. Cyanobacteria literally terraformed Earth by pumping oxygen into the atmosphere during the Great Oxidation Event, making it possible for complex life (like you, reading this right now) to exist. They basically invented breathable air as a waste product. Talk about a glow-up. So next time you take a deep breath, maybe send a little thank you to those microscopic blue-green heroes instead of looking skyward. They're still out there in the oceans, doing their thing, keeping the oxygen cycle running, and getting zero credit for literally creating the conditions for all aerobic life on Earth.
