    How long man has been on earth is a very controversial question. Scientists say that man has walked the earth for approximately 90,000,000 years or roughly 90 million years. Look here for more information: http://www.historyworld.net/wrldhis/PlainTextHistories.asp?historyid=ab12#

    About 200,000 years
