The Indus valley civilization was one of the largest and most complex bronze age civilizations in India

The Indus Valley Civilization was one of the earliest civilizations in the world. It is also one of the oldest civilizations in the world. The Indus Valley Civilization was located in what is now Pakistan and northwest India. The Indus Valley Civilization had a lot of similarities to other ancient civilizations, such as Mesopotamia and Egypt. They all had a similar writing system, religion, and architecture. 

The Indus Valley Civilization was one of three "Ancient Eastern'' societies considered the cradle of civilizations in the ancient human world and one of the most widespread; the other two societies of the "Ancient Eastern" were Mesopotamia and Pharaoh Egypt. The lifespan of the Indus Valley Civilization is generally divided into three phases: Early Harappan (3300-2600 BC), Mature Harappan (2600-1900 BC) and Late Harappan (1900-1300 BC year).

The Indus Valley Civilization is considered a Bronze Age society; the inhabitants of the ancient Indus Valley developed new technologies in metallurgy - the science of working copper, bronze, lead and tin. Harappans also make intricate handicrafts using products made from the semi-precious stone carnelian.

However, there were also some differences between these three civilizations. For example, while Mesopotamia and Egypt were both located on rivers, the Indus Valley Civilization was not located on a river. The Indus Valley Civilization had written languages that were used for their recorded history. The system of writing was mostly used to create an alphabet and to express syllables, not necessarily words. 

 The first use of writing is unclear. The earliest known texts are inscribed on pottery, dating from as early as 3200 BC in the late Neolithic period. . The earliest of these is a fragment of a libation vase from Aksum, Ethiopia, containing an inscription recording the name of King Narmer.

The earliest texts in the other old-world writing systems — Egyptian hieroglyphs, Chinese characters — are also found on pottery. Ancient Sumerian cuneiform texts were inscribed on clay tablets before 3400 BC. The current version was transcribed by Sargon of Akkad in the reign of S argon's grandson Naram-Sin in the late 3rd millennium BC.

There is evidence of written language dating back to around 3400 BC in ancient Sumer, which reached its height between 2600 and 2200 BC, when it used cuneiform script. The oldest known writing system is Linear A (also called Proto-Linear A or Old Linear A), which was used to write on clay tablets as early as 3100–2800 BC. 

Cuneiform writing took over completely Several websites contain images of these inscriptions and reliefs, including that of a female figure holding her newborn and several animals, with an inscription left by another woman. The earliest known script from Ancient Egypt was found by archaeologists in the Indus Valley Civilization (3300-1300 BC). 

It is called Hier. This civilization also had a religion that centered on a deity called "Dumuzi." The civilization also had an architectural style that made it the tallest building in the world until modern times.
