As the title of this book denotes, Old Earth Creationism, which is the view held by creationists who believe that the earth may be extremely old, is being attacked not only by atheists and evolutionists, but also by those of the Young Earth Creationism view. Within the chapters of this book, I discuss reasons for seeing biblical substantiation and confirmation for an ancient earth, that has possibly existed for many eons of ages and that predates the creation of Adam and his domain (the current dispensation), by possibly millions or even billions of years. The creationist view that provides the most substantiation for this fact, is the one called "The Genesis Gap" (also referred to as "The Ruin-Reconstruction Theory" and "The Gap Theory"). We of the Genesis Gap view of Old Earth Creationism, believe that a past dispensation (or dispensations - plural) on the earth, likely included periods such as the dinosaur age. We do not claim to have absolutes or details regarding this age on earth, before Adam but we are firmly convinced that such a period is clearly revealed in God's Word. With this being the case, we are inspired to defend the Genesis Gap position. It is my sincere hope to contribute toward achieving that goal, within the chapters of this book.
