The development of rock inscriptions is closely linked to the development of communication signs of languages. The first rock inscriptions were likely pictographs, which are images that represent objects or ideas. As languages evolved, so did the symbols used in rock inscriptions. Gradually, pictographs were replaced by more abstract symbols that represented sounds or syllables. This led to the development of true writing systems, which could be used to represent any word or phrase.

Rock inscriptions played an important role in the development of human communication. They helped to spread knowledge and ideas across cultures, and they provide us with a valuable record of the past.

Here are some examples of rock inscriptions from different cultures:

* The Indus Valley Civilization (3300-1900 BCE) in South Asia is known for its complex system of pictographic writing.

Rock inscriptions continue to be used today by some cultures, such as the San people of southern Africa. They use rock paintings and engravings to communicate their history, beliefs, and traditions.

Rock inscriptions are a fascinating and important part of human history. They provide us with a glimpse into the past and help us to understand how our ancestors communicated.
