"The roots of the young earth movement are with a man named George McCready Price, a Seventh Day Adventist from the 1900s.ÃƒÆ’Ã¢â‚¬Å¡Ãƒâ€š He was a loud voice in the move to promote six 24-hour day creationism, starting around 1902.9, 10ÃƒÆ’Ã¢â‚¬Å¡Ãƒâ€š Although the Seventh-Day Adventists are now not as restrictive, their statements on creation have deep roots.ÃƒÆ’Ã¢â‚¬Å¡Ãƒâ€š In fact, the modern movements, led by Answers in Genesis, the Institute for Creation Research, and Kent Hovind, have their roots in Mr. Price. Why did the father of young-earth creationism, Price, preach so adamantly about creation? Seventh Day Adventists claimed that they had a vision, in which they saw the creation of the world in six 24-hour days. Thus, you could easily say that today’s young earth movement is based on a vision (someone’s dream?)ÃƒÆ’Ã‚Â¢ÃƒÂ¢Ã¢â‚¬Å¡Ã‚Â¬Ãƒâ€šÃ‚Â¦not a solid base upon which to make a real doctrine!"http://www.answersincreation.org/doctrine.htm
"George McCready Price (1870 — 1963) was a Canadian-American creationist. He produced a string of anti-evolution, or creationist works, particularly on the subject of "flood geology". However, not until after his death did his views become common amongst creationists.
Price was born in Havelock, New Brunswick, Canada. His father died in 1882 and his mother joined the Seventh-day Adventist Church. He married in 1887 another follower of the Seventh-day Adventist church. She was older than him.
Price then became a schoolteacher, teaching as a missionary at Battle Creek College (now Andrews University) between 1891 and 1893 at another school in 1896 and at a high school in Tracadie, a Francophone fishing village, between 1897 and 1899.
He met Alfred Corbett Smith socially, who amused by Price's fundamentalism, introduced him to literature on science. Since his faith held that the Earth was young, Price concluded that geologists had misinterpreted their data.
In 1902 Price self-published Outlines of Modern Christianity and Modern Science. After failing as a preacher, and then as a writer in New York, Price helped build the then Seventh-day Adventist headquarters in Maryland and a school in California. In 1906 he self-published Illogical Geology.
He took a job as a secondary teacher with the Adventists but then took 1921 off to write The New Geology. In 1924 Price was sent to Stanborough Missionary College, in Watford, London, United Kingdom."http://en.wikipedia.org/wiki/George_McCready_Price
Personally, I believe in the day-age theory and would recommend Hugh Ross.
