* Evolution, Not Invention: The Greek alphabet didn't spring up overnight. It evolved over a period of time, borrowing and adapting from the existing Phoenician alphabet. This process likely spanned decades, if not centuries.
* No Written Records: We don't have detailed records from that period explaining the precise steps and timeframe of the alphabet's development.
* Gradual Change: The alphabet's evolution wasn't a single event, but rather a series of gradual changes and refinements.
However, we can provide some general estimates:
* Phoenician Influence: The Greek alphabet emerged around the 8th century BCE, influenced by the Phoenician alphabet.
* Early Adoption: The earliest known Greek inscriptions date back to the 8th century BCE, showing the alphabet was already in use.
* Evolution and Refinement: It likely took several decades for the Greek alphabet to fully develop and solidify its distinctive features, such as the inclusion of vowels.
In conclusion: While we can't give a precise timeline, it's safe to say that the development of the Greek alphabet was a process that took place over a significant period, likely spanning several decades.
