Happy New Year Joseph,
snipped some
CREA
You frequently see creationist literature that presents arguments that
the present population is an entirely reasonable extrapolation from Noah &
family. However, a little analysis proves this to be one of the
creationists' weakest links. I have read Henry Morris stating that the
entire current population can be accounted for if we assume a doubling rate
of 150-170 years. This, of course assumes an absolutely uniform rate of
growth and ignores wars, famines, pestilences, etc. The fatal flaw in this
scenario is that if it is true, then when Moses began the Exodus there were
less than 100 persons living in the entire world (and Exodus claims that
some 600,000 men of fighting age along with their fathers, mothers, wives,
sisters and minor children were involved!).

What it does demonstrate is that creationists aren't very good at
math and that the assumptions regarding growth rates and mortality rates
are invalid. The Institute for Creation Research folks' mathematical models
tend to be overly simple. (Remember the average education level of
fundamentalists who buy ICR books!)
The world's net population historically doesn't double at anywhere near
that rate. Try re-running the numbers with the following assumptions:
1) An equal number of males and females are born each generation
2) All children live to full reproductive adulthood
2) The entire race procreates (i.e. all couples produce children)
3) Each breeding couple produces only four children (i.e. doubles) then
dies.
When you use these parameters and a basic spreadsheet program, you'll end
up taking only 33 biblical 40-year generations (about 1,280 years) to
achieve over 8 billion living population. (For a real chuckle, try running
the numbers out to the ICR's earth age of 6000 years and see what you get!)
When run with a population doubling every 160 years, as Morris is cited as
claiming, (splitting the difference between 150 and 170), it takes 5,121
years to reach 8.6 billion population.
Thus, the creationists can prove there had to be a flood! (Notice my tongue
firmly in my cheek here!!) Otherwise, with Morris's 6,000 year old earth,
we'd have almost 275 billion humans born in this generation. The only
problem is that we're missing about 269 billion people... (Or could it be
that ICR's simplistic models are ridiculous???)
