Authenticity of the book of Daniel

The book of Daniel has been fiercely attacked by many, and especially its authenticity remains a subject of great controversy.  The detailed prophecies contained in the book have motivated scholars and laymen alike to adopt the theory of a late date of composition in the time of the Maccabees, claiming that the book of Daniel was written around 168-165 B.C. In this article, Dr. Roger Liebi invalidates the theory by systematically refuting many of the arguments presented.
