Events, or “things happening”, but there’s no real distinction between major or minor events, natural occurrences or “artificial” events initiated by living things, it’s all just shit happening all the time. A leaf falling from a tree, a baby being born, light reaching the Earth, a bomb going off, a gust of wind blowing, an ant dying, a barn getting raised, an asteroid smashing into a planet, someone picking their nose, a symphony plays, a baby cries, someone orgasms, crickets chirp, a body decays, a TV personality talks, the Earth rotates, the Sun radiates, a teacher speaks, a star is collapsing, rain is falling, a shot is fired, and on and on and on, everywhere all the time. “Everything” or “Life” as answers probably also work.
