9500 B.C. to 8000 B.C.
Exactly when the first people discovered America is one of the most hotly debated subjects in American archaeology. There is increasing evidence that people arrived in the New World before the Clovis culture (9500 B.C. to 8000 B.C). Sites such as Meadowcroft Rockshelter in Western Pennsylvania and Monte Verde, Chile, indicate that people have been here since at least 13000 B.C. Evidence from sites such as Topper, South Carolina hint that people may have been in America even earlier.
