From http://www.heritageinstitute.com/zoroastrianism/zarathushtra/; "There are no written records from Zarathushtra's time. The earliest surviving written references to Zarathushtra are those of Greek writers from about 2,500 years ago (see below). They in turn quote earlier sources now lost to us. Zarathushtra in the estimation of the Greeks, lived some 6,000 years before their time, or 8,200 to 8,500 years ago.". Zoroastrianism has a history dating from 600 BC to perhaps more than 1000 BC. The total number of currently practicing Zoroastrians is unknown but estimates range from about 125,000 to over 300,000. Most Zoroastrians live in their traditional homelands of India, Pakistan, Iran, Afghanistan and Azerbaijan; presently a substantial proportion of the population lives in places such as North America, the United Kingdom, the Persian gulf, Oceania, and Singapore. The Parsi and Irani groups are some of the most well known people that have been reported to still practice this religion. Historically Zoroastrianism was widespread across much of Central Asia, Anatolia, Babylon and its birthplace, Persia.
