Amazon river was formed 9 million years ago:

Netherlands and Brazil-based researchers have determined the Amazon River was formed more than 9 million years ago. Chemical analyses of sediments from an exploration site in Brazil revealed changes in their composition around 9 million years ago. Researchers said that it represented a source shift from lowlands to Andes mountains, a diagnostic of the onset of the transcontinental Amazon River.

The research was carried out in the context of the Clim-Amazon project, a joint Brazilian-European scientific initiative for climate and geodynamic research on the Amazon River Basin sediment and is supported by the EU (European Union) through the FP7 (Seventh Framework Programme for Research and Technological Development).
