The reason the earliest inscriptions in the Indian subcontinent were written in the Brahmi script in Prakrit is based on historical and epigraphic evidence.

Brahmi Script: The Brahmi script is one of the oldest scripts used in India and is considered the precursor to various Indian scripts, including Devanagari, Tamil, Telugu, and others. It was developed during the Mauryan period, around the 3rd century BCE, and is associated with the emperor Ashoka.

Prakrit Language: Prakrit is an ancient and popular language in India that was used for various inscriptions, especially during the Mauryan and Shunga periods. It was a vernacular language used by the common people and was distinct from classical languages like Sanskrit.

Early Inscriptions: Some of the earliest known inscriptions in India, such as the inscriptions of Ashoka, were written in the Brahmi script and the Prakrit language. These inscriptions are significant historical records that provide insights into the social, political, and religious aspects of ancient India.

While Sanskrit and Pali were important languages in ancient India, the Brahmi script in Prakrit was the script used in some of the earliest inscriptions discovered in the Indian subcontinent.
