History
Amazon river flowed westward, perhaps as part of a protoCongo (Zaire) river systems from the interior of presents day Africa.
Fifteen million years ago, the Andes were formed by the collision of the South American plate & Nazca plate.
The rise of the Andes & the linkage of the Brazilian & Guyana bedrock shields, blocked the river & caused Amazon become a vast inland sea.
