"From the shape of the letters, it is clear that the Greeks adopted the alphabet the Phoenician script, mostly like during the late 9th century BCE. In fact, Greek historian Herotodus, who lived during the 5th century BCE, called the Greek letters "phoinikeia grammata" (φοινικήια γράμματα), which means Phoenician letters."
About Linear A
Late in the 19th century CE, the English archaeologist Sir Arthur Evans published a paper named ‘Cretan pictographs and the prae-Phoenician script’, based on the study of a number of signs and short inscriptions found on Crete and mainland Greece.
Sir Arthur says "prae-Phoenician script’" so What are the other theories about Linear A ?
