Serbs had alphabet before Cyril And Methodius

The Vinča culture, [ʋîːntʃa] also known as Turdaș culture or Turdaș–Vinča culture, was a Neolithicarchaeological culture in southeastern Europe, in present-day Serbia, and smaller parts of Bulgaria, Kosovo, Macedonia and Romania (particularly Transylvania), dated to the period 5700–4500 BC or 5300–4700/4500 BC.^[1][2][3] Named for its type site, Vinča-Belo Brdo, a large tell settlement discovered by Serbian archaeologist Miloje Vasić in 1908, it represents the material remains of a prehistoric society mainly distinguished by its settlement pattern and ritual behaviour.
Farming technology first introduced to the region during the First Temperate Neolithic was developed further by the Vinča culture, fuelling a population boom and producing some of the largest settlements in prehistoric Europe. These settlements maintained a high degree of cultural uniformity through the long-distance exchange of ritual items, but were probably not politically unified. Various styles of zoomorphic and anthropomorphicfigurines are hallmarks of the culture, as are the Vinča symbols, which some conjecture to be the earliest form of proto-writing. Although not conventionally considered part of the Chalcolithic or "Copper Age", the Vinča culture provides the earliest known example of coppermetallurgy.

Cyril and methodius only just made some improvements, they never invented this script.

[Renekton]

If I remember correct Serbs adopted the Glagolic writing system first and later the Cyrillic.

So I believe yes the have prior to the Cyrillic writing system another one

[Linebacker]

Mental gymnastics.

The Fyromians are even bolder than the Serbs, since they claim Cyril and Methodius were "ethnic Macedonians" whatever they believe that meant at the time.

The Vičansko pismo looks very similar to the Cyrillic alphabet bulgarians like to claim as their own, except it predates it by a few thousand years!

Bulgars were Turkic speakers, so funny they claim a Slavic alphabet

Serbs never used Glagolitic, it was used almost exclusively by Croats.

True. Serbs use Cyrillic script from its beginning.
