Did the first Americans come from...France? “America's Stone Age Explorers” examines several theories about how and when the New World was first populated. Many scientists dispute the long-standing theory that the first to arrive crossed a “land bridge” from Asia some 13,500 years ago, because artifacts much older have been found in Pennsylvania, Texas, Virginia and Chile. Some believe the Solutreans crossed the Atlantic from France and Spain around 17,000 to 18,000 years ago.
