It was writing that took man in to the history, there are all kind of writing system invented by ancient civilizations but what kind of writing took man in to the history? 
Linear cuneiform 2500 BC was a starting point and it was invented by Sumerian.
Early cuneiform inscription used linear inscriptions by using a pointed stylus and on occasion called "linear cuneiform", before introduced to the new wedge styluses. However the recent discoveries in Jiroft changed everything upside down.
Iranian plateau had two types of writing language:
1. Proto-Elamite script, which was mostly figures and numbers.
2. Linear Elamite was writing language which did not use figures, it was syllabic writing system.
Previously to the discovery of Jiroft inscription, the most ancient script had been found in Susa site which has remained from the the period of rule of a monarch of Khutelutush-In-Shushinak and its dates back to 1200 BCE. It was always though that cuneiform was introduced by Akadian to the Elamite around 2200BC. According to Majidzadeh; “It is believed that Jiroft’s writing language came into existence at the same time Mesopotamia started developing a writing system. According to the carbon 14 tests conducted on the layers in which Jiroft inscription was discovered, this inscription was dated to 2500 BCE. Although such tests have not been carried out on Mesopotamia inscription yet, based on the discovered evidence so far, archaeologists strongly believe that Mesopotamia’s script goes back to 2600-2700 BCE at most”.
Please NOTE: The inscriptions unearthed in Jiroft was found on top of the layer, it believed that there are lots of artefacts buried in 12 meters beneath of Konar sandal (in Jiroft) and also the archaeology discoveries that carried out in Sumer, took 200 years but in Jiroft only took seven seasons.
Both Linear Elamite and Linear cuneiform (Sumerian Language) were both oldest writing system (invented at the same time) the Linear language after developed to typical wedge shaped sign called cuneiform.
The so called Linear Elamite writing is completely independent from the cuneiform writing system Created after the vanishing of the Proto- Elamite tablets, Thought to be the Linear writing was mainly limited to Susa and Puzur- Inšušinak’s era(2100 BC). The findings, mainly in the Konar Sandal (Jiroft) and Shahdad, show that this writing system was probably created in the second half of the 3rd millennium BC in southern Iran. The beginning of the 2nd millennium BC, the cuneiform writing system probably played an important role at that time in the rejection of the Linear writing system in south- western Iran. Also the Linear writing system was probably limited to a small community of users or at least much smaller than the cuneiform and specially used for royal inscriptions!
We have developed two different tools, one is the Linear Elamite and other is Old Persian (Cuneiform) to get familiar and examine the language.
Please NOTE: the Linear Elamite tool is not for learning purpose it’s for fun and to get familiar with the sign and their writing system.
