The first humans that came to the Americas used probably the Bering Bridge or oceanic routes using stone age technology. It is believed that humans have been in the Americas, both North and South, from more than 30000 years. More or less for the same time evidence of dwarf settlements are found in North America. The most ancient evidence of dwarves in South America are dated from 3000 years ago, which suggest that they came as slaves and escaped into the high mountain regions in the Andes. Here, archeological and written evidence concurs. There is no single evidence from elves prior the age of inter-oceanic exploration (AIOE).
Given recent genetic research it is believed that pre-AIOE humans come from East Eurasia, West Eurasia (Europe), Africa and Oceania, which enforces the idea of multiple routes. Statistical analysis also suggest that North America was peopled originally from East and West Eurasia and South America from Oceania and Africa, but this evidence is non-conclusive yet, given the displacements of people in both the Old and the New Worlds.
The first agricultural cultures in the Americas are placed in the Amazonian forest, where maize and manioc where domesticated, around 8000 years ago. However those Amazonian cultures never developed beyond than semi nomadic subsistence agriculture. Maize spread to the Andes and then to the Caribbean and North America. In both the Andes and Mesoamerica, permanent settlements begun around 7000 BP. Those permanent settlements expanded into the Paraná and the Mississippi plains where the first American high civilizations arose about 6000 BP.
The first Paraná civilization (bla-bla-bla). However the prosperity of the Paraná civilization attracted peoples from both the Andes and the Plains which always challenged the centralized organization. When the Bolivians finally attacked in 5124 BP, the first Paraná civilization was officially dismissed.
When the fist Paraná civilization ceased, several cultures had arisen in the Andes valleys and highlands. The main cultures in South America were the São Paulo, the Uruguay, the Chiloé, the Santiago, the Cochabamba, the Poopo, the Tititaca, the Cuzco, the Salvador, the Recife, the Guayaquil, the Cauca, the High Magdalena, the Bogotá, the Santa Marta, the Barinas, and the Sinú.
