How old was the First known Alphabet?

Alphabet - is the oldest known alphabet was found in Greek inscriptions of about 2000 B.C. The word comes from the first two words of the Greek alphabet, alpha and beta. The alphabet invented in Greece was based on north Semitic writing and was made up entirely of consonants. This was suitable for a Semitic language but not for a Sudo European one such as Greek.

There are two forms of the Greek alphabet called Chalcidic and lonic and generally known as Western and Eastern. The Western symbols were brought to Italy by Etruscans and Greek colonists and adapted to form the Latin alphabet used today in most English speaking European and American countries.
