Your question titling this thread is a bit confusing.
an uninterrupted segment of speech consisting of a vowel sound, a diphthong, or a syllabic consonant, with or without preceding or following consonant sounds.
An alphabet is a standard set of letters that is used to write one or more languages based upon the general principle that the letters represent phonemes of the spoken language. This is in contrast to other types of writing systems, such as syllabaries and logographies.
Do you have an example of an alphabet that is Not syllabic ?
That is why i prefaced my first post with the term 'complex language', meaning one that uses vowels, consonants, dippitydoothongs, etc and combines those sound elements in a complex way to convey a wide range of meanings. Here that language has also, over time, abstracted and condensed those sounds into a set of 'glyphs' which can be combined in complex (learned) way to convey meaningful words.
Spelling words that were originally spoken or conveyed with "sign (gestural) language", (which while still used today is often left out of discussion on the development on Language).
That out of the way, it's back to the question of how and where the written symbolization of language began.
Take a vast field of say, sunflowers. All look alike and taste the same until one day there is a sort of "Carrington Event" and the strong radiation causes a mutation in one of the seeds. Bingo, the next season there grows up a much larger and tastier sunflower plant. These days of course a small group of clever botanists can do the same thing in a lab.
A corny example to be sure, but why couldn't the same thing happen to the global population of early humans ?
Looking at the immense body of myth, and the collected history of post-ice age migrations; i've come to favor the hypothesus that the quantum leap in cortical development, language, invention, construction and the whole gestalt we referent to as high civilization occurred in the region of that natural hemispheric crossroad between the Caspian and Black seas.
