Archaeologists have discovered what may be the world’s oldest emoji — a smiley face painted on a 3,700-year-old piece of pottery. During an excavation at an ancient city whose remains are in modern-day Turkey near the Syrian border, archaeologists found the ancient pitcher with three visible paint strokes on it — two dots for eyes and a curve for a smile. The pitcher, which dates to about 1,700 BC, was found in a burial site beneath a house in Karkemish. The pitcher was likely used to drink sherbet, a sweet beverage.
