Both Trinidad and Tobago were originally settled by Amerindians who came through South America. Trinidad was first settled by pre-agricultural Archaic people at least 7,000 years ago, making it the earliest settled part of the Caribbean. Banwari Trace in south-west Trinidad is the oldest attested archaeological site in the Caribbean, dating to about 5000 BC. Several waves of migration occurred over the following centuries, which can be identified by differences in their archaeological remains. At the time of European contact, Trinidad was occupied by various Arawakan-speaking groups including the Nepoya and Suppoya, and Cariban-speaking groups such as the Yao, while Tobago was occupied by the Island Caribs and Galibi. Trinidad was known to the native peoples as "Ieri" ("Land of the Humming Bird").
