This is Part 4 of the ten part blog debunking the claims made on CreationEvidence.org’s “Evidence for Creation.” This blog examines point #4.
NOTE: Because of the nature of the argument presented in point #4, this blog will not examine the argument sentence by sentence, but will address the argument as the whole.
STATEMENT: “World population growth rate in recent times is about 2% per year. Practicable application of growth rate throughout human history would be about half that number. Wars, disease, famine, etc. have wiped out approximately one third of the population on average every 82 years. Starting with eight people, and applying these growth rates since the Flood of Noah’s day (about 4500 years ago) would give a total human population at just under six billion people. However, application on an evolutionary time scale runs into major difficulties. Starting with one “couple” just 41,000 years ago would give us a total population of 2 x 1089. The universe does not have space to hold so many bodies.”
RESPONSE: The basis for this argument is a work by Henry Morris called Scientific Creationism. It has several flaws in it, but I will deflect to Lenny Flank, Jr., author of Deception by Design: The Intelligent Design Movement in America, who states:
“Contrary to Morris’s fanciful assumptions, there is no reason to believe that the global human population has been increasing exponentially, and good reason to believe that it was in fact stabilized by environmental factors (just like the housefly population has been) throughout most of human history, right up until the agricultural and industrial revolutions which have allowed population growth rates to climb sharply. Morris’s population argument is nothing more than an exercise in story-telling, and in it we see the basis for the other stories told by the creationists–selecting a short term trend and then projecting and extrapolating it backwards until it reaches the desired result.” (Lenny Flank, Population Rates and the Age of the Earth)
Regarding the statement about evolution, I would like to know why we must assume that we are starting from one couple 41,000 years ago. Why? Evolution does not ask that we start from one couple, as evolution is a slow, progressive process. And no one thinks that the human species originated 41,000 years ago. Actually, it is believed to have been more like 200,000 years ago. So why these arbitrary numbers? While the math they present is accurate, the argument itself is based on the false premise that population growth occurs at a constant, exponential rate. As Flank says, “While Morris’s mathematics are impeccable, the reasoning behind his argument is shoddy at best.”
