Here's a breakdown of why the question is difficult to answer:
* "Aryan" is a historical and linguistic term, not an ethnic one. It's used to refer to a group of Indo-European peoples who migrated into India and other parts of Asia from around 2000 BCE onwards. Their language, Proto-Indo-European, gave rise to many modern languages, including Sanskrit, Hindi, Persian, and English.
* "Aryan villages" is a very broad term. It could encompass a vast geographic area and a wide range of time periods. During the Vedic period (around 1500-500 BCE), people speaking Indo-Aryan languages lived in various parts of the Indian subcontinent, likely in villages and settlements.
* The earliest writing systems used in India were not directly linked to the Indo-Aryan languages. The Indus Valley Civilization (c. 3300-1300 BCE) had a sophisticated writing system that remains undeciphered. Later, around the 6th century BCE, the Brahmi script was developed and adapted for writing various languages, including Sanskrit and Prakrit, which were spoken by Indo-Aryan peoples.
Instead of focusing on "Aryan villages," it's more accurate to talk about the development of writing systems in ancient India:
* The Indus Valley Civilization script: This remains undeciphered, but it's possible it was used for writing a language related to the Indo-Aryan languages.
* The Brahmi script: Developed around the 6th century BCE, this script eventually became the basis for many Indian scripts, including Devanagari, used for writing Hindi and Sanskrit.
* Sanskrit: This ancient Indo-Aryan language, considered a sacred language, was written using various scripts, including Brahmi and its later derivatives.
Therefore, it's more accurate to say that the written languages used in ancient India developed gradually over time, with the Brahmi script playing a crucial role in spreading literacy and preserving knowledge.
