I purchased this as a print edition over a decade ago. It should be a must for every Christians Library, especially every Christian parent's library. A well concealed fact by the education industry is that over 90% of the possible methods for dating the earth yield a result much much shorter than the accepted age of the earth. One of the indicators of the earth's age, the decay of the magnetic field, indicate that it is impossible for the earth to be older than 30K years. Older than that the magnetic field would be so strong the earth would be molten. The author also reveals the tricks the geologists use to ensure they get the 'right' date from their samples.
