Hugh Norman Ross (born July 24, 1945) is a Canaian-born Old Earth creationist and Christian apologist. An astronomer and astrophysicist by training, he has established his own ministry called Reasons To Believe that promotes forms of Old Earth creationism known as progressive creationism and day-age creationism. Ross accepts the scientific evidence of the age of the earth and the age of the universe, but he rejects evolution and abiogenesis as explanations for the history and origin of life.
