What Happend to the Ancient Advanced Cultures of the Amazon?

Were you aware that where there is now the dense jungle of the South American Amazon, there was, some 3,000 to 4,000 years ago a vast stretch of inland water?

THE AMAZON SEA

When man first settled South America, the whole Amazon basin was a shallow inland sea.  Into the great inland Amazon Sea, many rivers flowed which are now the arms and feeders of the great Amazon River.

And also at that time there was no mountain range between the Amazon and the Pacific Ocean.  The Amazon Sea connected naturally with the Atlantic Ocean in the east and with the Pacific in the west, by canals.

These canals remained intact until the Andes mountains were raised suddenly. But that is something for another time.

The shore lines of this inland sea are distinctly visible today:

1.The northern shores:  Along the foothills of the Venezuelan highlands are beautiful white quartz beaches.

2.The western shores: Along the eastern foothills of the Andes, these shorelines can also be seen.
