Here's why:
* All written languages have a writing system. This system might be an alphabet, syllabary, abjad, or logographic system. Each system has its own set of symbols representing sounds or concepts.
* Many languages use different writing systems. For example, Chinese uses logographic characters, Japanese uses a combination of logographic characters and syllabaries, and Arabic uses an abjad.
* "Alphabet" is not the only writing system. While alphabets are the most common system in the world, other systems exist and function just as effectively for their respective languages.
Therefore, no language is truly "alphabet-less." Every language with a written form uses a specific system to represent its sounds or concepts.
