* The Neolithic period spanned thousands of years and covered vast geographical areas. The New Stone Age began around 10,000 BCE and ended around 3,000 BCE, with significant variations in different parts of the world.
* Written language was not widespread during the Neolithic period. The earliest known written languages emerged around 3,200 BCE in Mesopotamia. Before that, communication was likely oral.
* Languages change over time. Even if we could decipher a Neolithic language, it would be vastly different from any language spoken today.
However, we can make some informed guesses based on:
* Linguistic studies: Comparisons of modern languages can help us trace relationships back to ancient languages. For example, the Indo-European language family is believed to have originated in the Neolithic period, and its descendants include English, Spanish, Hindi, and many others.
* Archaeological evidence: Study of artifacts, tools, and settlements can reveal clues about the cultures of Neolithic peoples, including their possible linguistic affiliations.
In short, we don't have a definitive answer to what language the people of the New Stone Age spoke. We can only make informed guesses based on the limited evidence available.
