Way way waaaaaaaay back in the day, free oxygen didn't really exist on our world. Things used other chemicals like certain sulfates to get energy.Also comes a certain microbe or bacteria that started an early form of photosynthesis where oxygen was a byproduct. Total gamechanger. Its like you have been living off bits of stale bread your whole life and suddenly you are given pizza every hour.So these microbes take off like a shot, just multiply and multiple, basically knock off anything else in the area, as nothing can compete with these little oxygen produces. And the oxygen builds and builds and builds.But...here's the thing... oxygen is actually an incredibly reactive poisonous material. Modern life has gotten used to dealing with it, but make no mistake, oxygen is TERRIBLE for you in many ways if you didn't have certain protections in place to keep it in check. Well the thing is back then NOTHING had protection from free oxygen....not even the oxygen producers themselves! It just wasn't necessary for life back then to have protection from oxygen.Until....suddenly the air (and eventually the water) was filled with the stuff...this toxic poisonous highly reactive substance was everywhere. And so....a mass extinction event occurred, some scientists speculate the greatest the earth has ever known. It basically almost destroyed life itself until certain lifeforms scurried away were able to create resistances to oxygen, and then life was able to branch out again.</blockquote>
