Asia
The coastal periphery was home to some of the world's earliest known civilizations, each of them developing around fertile river valleys. The civilizations in Mesopotamia, the Indus Valley and the Yellow River shared many similarities. These civilizations may well have exchanged technologies and ideas such as mathematics and the wheel. Other innovations, such as writing, seem to have been developed individually in each area. Cities, states and empires developed in these lowlands.
Minoan civilization
The most well-known script is Linear A, dated to between 2500 BC and 1450 BC. Linear A is the parent of the related Linear B script, which encodes the earliest known form of Greek. Several attempts to translate Linear A have been made, but consensus is lacking and Linear A is currently considered undeciphered. The language encoded by Linear A is tentatively dubbed "Minoan". When the values of the symbols in Linear B are used in Linear A, they produce unintelligible words, and would make Minoan unrelated to any other known language. There is a belief that the Minoans used their written language primarily as an accounting tool and that even if deciphered, may offer little insight other than detailed descriptions of quantities.
