What source is the most reliable source for ancient history?In: Ancient History [Edit categories][Edit]AnswerStrange as it may seem, the Bible has repeatedly been proven as a reliable historical source in relation to the history with which it deals. In the nineteenth century period of biblical skepticism almost everything in the Bible was questioned and doubted as being historically inaccurate and unreliable. Since this time over 5000 archaeological discoveries have been documented in a multi-volume work by archaeologist Dr. Clifford Wilson. These discoveries, mostly relating to the Old Testament and many to the New are in the museums and private collections of the world.According to Dr. Wilson and others, not one single discovery of archeology has ever refuted a biblical assertion. This is an astounding fact, especially when considering the large span of time covered by the biblical record.
