However, Martín Fernández de Enciso , a member of the Vespucci and Ojeda crew, gave a different account. In his work Summa de geografía , he states that the crew found indigenous people who called themselves the Veneciuela. Thus, the name "Venezuela" may have evolved from the native word. 
Evidence exists of human habitation in the area now known as Venezuela from about 15,000 years ago. Leaf-shaped tools from this period, together with chopping and planoconvex scraping implements, have been found exposed on the high riverine terraces of the Rio Pedregal in western Venezuela.  Late Pleistocene hunting artifacts, including spear tips, have been found at a similar series of sites in northwestern Venezuela known as "El Jobo"; according to radiocarbon dating , these date from 13,000 to 7,000 BC. 
After the conquest, the population dropped markedly, mainly through the spread of new infectious diseases from Europe.  Two main north-south axes of pre-Columbian population were present, who cultivated maize in the west and manioc in the east.  Large parts of the llanos were cultivated through a combination of slash and burn and permanent settled agriculture.
