@Malik Barnes Thank you

1. Geocentric universe: Earth at the centre, everything revolves around us-until Copernicus and Galileo flipped it heliocentric in the sixteen hundreds. 2. Flat Earth: Thought true forever, but proven round by ancient Greeks like Aristotle via lunar eclipses and ship horizons. 3. Four humours medicine: Blood, phlegm, yellow bile, black bile caused illness; bloodletting was standard till germ theory hit in the eighteen hundreds. 4. Alchemy turning lead to gold: Pursued for centuries as real chemistry, debunked by modern atomic understanding-no such transformation without nukes. 5. Sun revolves around Earth: Ptolemys model lasted thirteen centuries, shattered by Kepler’s orbits and telescopes showing phases of Venus. 6. Dinosaurs as lizards: Early views had them sluggish reptiles; now we know many were feathered, warm-blooded dynamos like T-rex. 7. Static continents: Believed fixed until Wegener’s nineteen ten plate tectonics theory showed they’re drifting puzzle pieces. 8. Phlogiston theory: Invisible substance caused burning, accepted till Lavoisier’s oxygen work in the seventeen seventies. 9. Atoms indivisible: Democritus idea held till Rutherford split them in nineteen eleven, revealing protons, neutrons, electrons. 10. Neanderthals as brutes: Seen as dumb cavemen; DNA shows they were smart artists, toolmakers, interbred with us modern humans.
