At the historic Scopes Trial in Tennessee in 1925, William Jennings Bryan, the prosecutor who stood for the Christian faith, failed to answer the question about Cain’s wife posed by the ACLU lawyer Clarence Darrow.
In recent times, this same example was taken up by Carl Sagan in his book Contact (which was on the New York Times best-seller list) and used in the movie of the same name based upon this work.
Sagan cleverly listed a number of common questions (including Cain’s wife) that are often directed at Christians in an attempt to supposedly prove the Bible is full of contradictions and can’t be defended.
The truth is—most Christians probably couldn’t answer these questions. And yet there are answers.
