The origin of the alphabet goes back to the Phoenician system of the 2nd millennium BC, from which the modern Hebrew and Arabic systems are ultimately derived. The Greek alphabet, which emerged in 1000–900 BC, developed two branches, Cyrillic (which became the script of Russian) and Etruscan (from which derives the Roman alphabet used in the West)

Early 16th century: from late Latin alphabetum, from Greek alpha, bēta, the first two letters of the Greek alphabet. We use them in today's math also as you know.

Nearly all modern alphabets are descended from an alphabet invented 4000 years ago, probably by a group of people related to the ancient Hebrews, Phoenicians, and Canaanites, living in what is now the Sinai desert. They got the idea from the Egyptians, but used their own simplified pictures to represented consonant sounds. The Phoenicians and others of the region simplified the pictures further and often rotated them, but if you use your imagination, you can still make out where most of the 22 letters came from. If you turn the A with the point down, for example, you can see a representation of an ox head.
