It is impossible to answer that question since many languages existed and became extinct before there was anyone around to record them - that is the precise meaning of "prehistory" and we can only know about those very ancient times from the archaeological record, which does not preserve language.
It is estimated that in South America there have been many thousands of native languages, many long extinct; there were around 1,500 at first European contact. In Meso-America (Central America) there have been an unknown number of native languages and dialects, certainly several hundreds.
In North America there have been anywhere between 300 and 700 languages and dialects, many of them extinct long before European contact. Many of the archaic languages are completely unknown, such as the language or languages of the Adena, Hopewell and Clovis cultures which may each represent more than one tribe.
It is estimated that there have been around 7,000 languages that have existed throughout human history.
As of 2009, there are approximately 434 extinct languages; 49 languages from Africa, 68 languages from Asia, 8 languages from Central America and The Caribbean, 64 languages from Europe, 99 languages from North America, 30 languages from Oceania, and 116 from South America.
It is estimated that there have been around 7,000 languages that have existed in human history, although many have become extinct over time. This number includes both known and undocumented languages, as well as ancient and modern languages.
