The Gap Theory shows evidence of the dinosaurs becoming extinct as the result of Satan's fall and explores the origin of demons as being disembodied spirits of a pre-Adamic race, who were judged by God, as the result of Satan's sin. Why was man commissioned by God in Genesis 1:28 to "replenish" the earth? Why did God use that word? Could this be a reference to a pre-Adamic race that was created in Genesis 1:1 and destroyed in Genesis 1:2 due to Satan's fall, and which the human was to "replace" or "replenish" Read where angels that sinned left their heavenly habitation and came down to earth to procreate with humans and whose children were called "Mighty men, which were of old, men of renown" offspring that are the source of all the ancient secular myths that claim the "gods" came down to earth and married human women.
This short book makes a strong case for the theological necessity of the gap theory, and highlights the failures of alternatives. Like Jesus and the Trinity, once one becomes aware of the concept, it can be seen written about and assumed throughout scripture.
The zeal of Young Earth Creationism has done many good things scientifically to show the impossibility of evolution and the weakness of 'conjectural science' dating methods, but it just cannot account for the multiple floods in the geologic record or the very old human populations proved to have existed. A YEC believer who recognizes the truth that Satan fell before Adam, and that there was necessarily a consequence of that fall, is then equipped to understand how the water in Gen 1:2 and of Noah's flood illustrate the consistency of God.
Someone editing the work needs to freshen up on the usage of then/than and proper use of apostrophes, but those minor distractions shouldn't detract from the sound theology of the work.
One minor disagreement I have with the book is that it says the seven literal days started after Gen 1:3. The Spirit moving on the face of the waters and then the appearance of light are similar to the dawn and daybreak of every day, in my opinion. It's clear the Genesis creation record literally uses a daybreak-to-daybreak framing of the six days.
The author should be commended for his courage and bravery to write such a book. Additionally, he has a truly gifted imagination. Bravo.
However, this book is mainly one large ball of assumptions rolled into one. There is no conversation with competing theories (other than name-calling and pronouncing some competing views as “silly”). The overall content and supporting evidence for any of the authors claims is just as lacking as the evolutionary fossil record: there are no connecting links between his assertions and his conclusions. The links are missing all over the place, or are pure conjecture, which the author readily admits (pg 39).
The author himself said it best, so I will use his words to describe my overall assessment of this work: “The sheets simply do not fit the bed” (pg 30).
