While there’s no concrete proof of the single oldest language, the oldest known languages are all languages from ancient civilizations around the fertile crescent: Sumerian and Akkadian. Sumerian is almost 5,000 years old and was spoken in what is now Iraq. Akkadian may be about the same age, though we can’t be sure, and was spoken by a different group in the same area. Egyptian may be even older (there are hieroglyphics that have been dated earlier). The oldest language still spoken today is Greek, which has been traced back about 3,500 years.
