Bill Wurtz is a YouTube musician and animator known for fast, jazz-backed explainers, and his history of the entire world, i guess, released in 2017, became one of the platform's most shared educational comedies. Lines from that video were clipped, remixed, and reused in short-form edits, where the sun line stood out because it compresses his whole style into a few seconds: calm narration, catchy music, and an unexpectedly dramatic claim. That brevity is why creators still reach for it when they want a quick, recognisable punchline.
