I just finished watching the depressing ending of Risen 2021 and the instant the end credits started I was hit with a realization - wasn't this what happened during the Great Oxygen Catastrophe? Anaerobic life existed on this planet for ~1.5 billion years before cyanobacteria came along. It wasn't alien life that did it but doesn't make much difference to me. I mean I appreciate (most of) my fellow humans but we're here because some microbes decided to terraform the planet, heedless of the planet-wide ecosystem they were destroying or the life that depended on it.

Anaerobic bacteria aren't humans and I'm sure they didn't have armies or scientists to realize they were doomed but at the bottom of it, life is life and extinction is extinction.

That crappy movie sure got me to thinking. To borrow a concept from Mark Twain, our actual history rhymes with this movie. Anyone else notice the parallels?
