This book has so many errors, many of which have never been corrected in subsequent reprints, even when Morris himself realized the errors. This book is a prime example of creationists' inability to accept when their pet ideas have been thoroughly debunked.
Though I had a hard time understanding some of this book, I do agree with the reader below that "this is probably the best single volume on the creation-evolution debate." Henry Morris and John Morris have a Trilogy out called "Modern Creation Trilogy" which goes more indepth about a wider range of topics. Though some of the stuff might be a review when reading it, I would still suggest reading them. Great books, the best books I've ever come across on the topic, and books that no evolutionist wants to have on the market. Morris is very Christ Honoring, as it should be.
This is the best work available, for gaining an understanding of how scientific facts fit into the creation model. Henry Morris brings his years of academic study and Bible knowledge together, in a way that can be understood by the laymen.
