The trace of written language has come up from Sumer in Mesopotamia. They are dated back to 3200 BCE. It is believed that the written language was evoked by temple priests, who were assigned to look after temples independently by the king. They had to keep the records of the expenditure and income of the temples. So they began to paint the items donated to the temples on clay tablet. In this, they began to keep these records. The temple of Uruk has revealed a list of 5000 such tablets. They engraved the pictures like signs and numbers of oxen, fish, etc. Now, it became easier to remember the things. In this way, the pictographic script came into prominence.
