A simple formula is derived which permits calculation of the population that will be produced from one initial pair in 77 generations, for any arbitrary number of children per family and generations per life span. On the basis of very reasonable and conservative assumptions, the traditional Biblical chronological framework of human history is found to be completely realistic. The evolutionary framework, on the other hand, is seen to lead to absurd and impossible conclusions. The human race is therefore, only a few thousand years old, instead of the million or more years claimed by evolutionists.
