The writing started with the Indus Script being written on a stone during 2500 BCE. The civilization did not use paper during the starting time of the establishment of their script.
The first form of language discovered was written in the Indian subcontinent, and the style remains undecipherable. The script used during the Harappan era is still taken as a mystery for not having any translation.
Though history about this civilization has been scripted, it is taken as the least famous and a mysterious culture as nothing written can be understood.
The earliest writings of Indus Script are found mostly in the pottery and few of the ornaments.
