The findings at Supe Peru (Caral) are very similar to sites in Egypt. The ground and terrain could be anywhere in the Middle East. A written language is a given considering the size of the site. As you stand in the middle you can not see the end of what was once a conglomeration of settlements. There is also evidence of clam shells that makes the site even larger. A grocery list, carried between farming and fishing communities only makes sense.
The idea that this concept is so foreign to sceintists is what is amazing. Of course there are far advanced civilizations in every corner of the world. The world is millions of years old. The world was conquered, settled, and thriving thousands and thousands of years before the Europeans formed gangs. The brutality of European warfare against the people of the world is the only shocking discovery of this century.
