Cave art suggests people inhabited Americas 30,000 years back

A new exhibit has suggested that Americas may have been inhabited as far back as 30,000 years ago, 18,000 years earlier than believed.

The common perception among most of the historians is that humans may have first crossed to the America from Asia 12,000 years ago.

100 items, which include cave paintings and ceramic art depicting animals, hunting expeditions and even love making scenes of the early Americans, have been displayed in Brasilia, Fox News reported.

The artifacts were discovered at the Serra da Capivara national park in Brazil's northeastern Piaui state that was a popular site for the hunter-gatherer civilization that created the artwork.

Franco-Brazilian archaeologist Niede Guidon, who has headed a mission to carry out large-scale excavation of Piaui's interior since the 1970's, said that charcoal remains of structured fires found at the site are among other traces of the Serra dwellers.
