Writing was invented in Mesopotamia around 3200BC, while in the Americas the necessity of writing things down triggered the same invention around 600BC. Main reason was because Eurasia was in the east-west plane where climate is similar and communication/commerce was not difficult to employ which helped Europe, ME, Asia, and far east to increase interaction. Americas on the other hand lays on the north-south plane, Isthmus of Panama is narrow to pass through, variances in climate and terrain greatly limited communication and commerce between north and south. When European showed up on the shores of Caribbeans and the mainland of Americas it was already too late.
