Where are all the people?
by Don Batten
Six billion people live on planet Earth. That sounds like a lot of people. Well, I would not want to invite them all to a barbecue at my house! However, they could all fit into an area the size of England, with more than 20 square metres each. Many of us live in cities, so we have the impression that the world is bursting with people. However, much of the world is sparsely populated.
Nevertheless, many wonder at how the population could have grown to six billion from Noah’s family who survived the Flood that wiped out everyone else about 4,500 years ago. When you do the figures, it confirms the Biblical truth that everyone on Earth today is a descendant of Noah’s sons and daughters-in-law. Not only that, but if people have been here for much longer, and there was no global Flood of Noah’s day, there should be a lot more people than there are—or there should be a lot more human remains!
Many people have problems understanding growth rates of things. When the population doubles from 16 to 32, it does not seem like much, but when it doubles from three billion to six billion it seems like a lot more. But, it is exactly the same rate of growth. Given enough generations, the number of people being added with each generation becomes astronomical. It’s like compound interest on an investment—eventually the amount being added each year becomes very great.
To illustrate this, think of the story of the inventor of chess. His king offered him a reward, but instead of gold he asked for one grain of rice doubled for each successive square on a chessboard. The number of grains would have been 1, 2, 4, 8, 16, 32 · etc. The 10th square would have 512; the 20th, 524 thousand; the 30th, 537 million. The amount of rice on the last square1 would have been a number so great—vastly in excess of the total world rice harvest at present—that it would have represented wealth far exceeding that of the king. Such is the power of compounding. And population growth is compound growth—that’s why so many people are now being added each year. It’s not necessarily that people are having more children than they once did, or that fewer people are dying.
What causes population growth?
The population grows when more people are born than die. The current growth
rate of the world population is about 1.7% per year.2 In other words,
for every 100 million people, 1.7 million are added every year; i.e. births
net of deaths.
Many assume that modern medicine accounts for the world’s population growth. However, ‘third world’ countries contribute most of the population growth, suggesting that modern medicine is not as important as many think.
Population growth in a number of South American and African countries exceeds 3% per year. In many industrialized countries with modern medical facilities, the population growth is less than 0.5%. Some relatively wealthy countries are actually declining in population.
The move from agriculture to manufacturing/technology has been a big factor in slowing population growth in industrialized countries. Farmers needed to have sons to help with the farm work. This was particularly necessary before mechanization. My own family records show that in the early- to mid-1800s in Australia, couples commonly had 8–10 surviving children. One couple had 16! And this was before the discovery of the germ basis of disease,3 aseptic surgery,4 vaccines3 and antibiotics. Opportunity to expand, combined with biology, saw growth in population of 4% or more, plus increases due to immigration. High rates of population growth were also seen in Quebec, Canada, from 1760 to 1790, following the British conquest of Canada in 1759,5 and well before the impact of modern medical knowledge.
In industrialized countries, the advent of social security pensions and retirement plans (superannuation) has probably been another major factor in the decline of population growth. These schemes mean that people do not see the need to have children for security in their old age. Furthermore, people can now easily choose how many children they have because of modern birth control methods, such as the contraceptive pill.
What growth rate is needed to get six billion
people since the Flood?
It is relatively easy to calculate the growth rate needed to get today’s
population from Noah’s three sons and their wives, after the Flood.
With the Flood at about 4,500 years ago, it needs less than 0.5% per year
growth.6 That’s not very much.
Of course, population growth has not been constant. There is reasonably good evidence that growth has been slow at times—such as in the Middle Ages in Europe. However, data from the Bible (Genesis 10,11) shows that the population grew quite quickly in the years immediately after the Flood. Shem had five sons, Ham had four, and Japheth had seven. If we assume that they had the same number of daughters, then they averaged 10.7 children per couple. In the next generation, Shem had 14 grandsons, Ham, 28 and Japheth, 23, or 130 children in total. That is an average of 8.1 per couple. These figures are consisent with God’s command to ‘be fruitful and multiply and fill the earth’ (Genesis 9:1).
Let us take the average of all births in the first two post-Flood generations as 8.53 children per couple. The average age at which the first son was born in the seven post-Flood generations in Shem’s line ranged from 35 to 29 years (Genesis 11:10–24), with an average of 31 years,7 so a generation time of 40 years is reasonable. Hence, just four generations after the Flood would see a total population of over 3,000 people (remembering that the longevity of people was such that Noah, Shem, Ham, Japheth, etc., were still alive at that time).8 This represents a population growth rate of 3.7% per year, or a doubling time of about 19 years.9
If there were 300 million people in the world at the time of Christ’s Resurrection,2 this requires a population growth rate of only 0.75% since the Flood, or a doubling time of 92 years—much less than the documented population growth rate in the years following the Flood.
A remarkable coincidence?
The Jews are descendants of Jacob (also called Israel). The number of
Jews in the world in 1930, before the Nazi Holocaust, was estimated at
18 million. This represents a doubling in population, on average, every
156 years, or 0.44% growth per year since Jacob. Since the Flood, the
world population has doubled every 155 years, or grown at an average of
0.45% per year. There is agreement between the growth rates for the two
populations. Is this just a lucky coincidence?
Hardly. The figures agree because the real history of the world is recorded in the Bible.
What if people had been around for one million
years?
Evolutionists claim that mankind evolved from apes about a million years
ago. If the population had grown at just 0.01% per year since then (doubling
only every 7,000 years), there could be 1043 people today—that’s
a number with 43 zeros after it. This number is so big that not even the
Texans have a word for it! To try to put this number of people in context,
say each individual is given ‘standing room only’ of about
one square metre per person. However, the land surface area of the whole
Earth is ‘only’ 1.5 x 1014 square metres. If every one of
those square metres were made into a world just like this one, all these
worlds put together would still ‘only’ have a surface area
able to fit 1028 people in this way. This is only a tiny fraction of 1043
(1029 is 10 times as much as 1028, 1030 is 100 times, and so on). Those
who adhere to the evolutionary story argue that disease, famine and war
kept the numbers almost constant for most of this period, which means
that mankind was on the brink of extinction for most of this supposed
history.10 This stretches credulity to the limits.
Where are all the bodies?
Evolutionists also claim there was a ‘Stone Age’ of about
100,000 years11 when between one million and 10 million people lived on
Earth. Fossil evidence shows that people buried their dead, often with
artefacts—cremation was not practised until relatively recent times
(in evolutionary thinking). If there were just one million people alive
during that time, with an average generation time of 25 years, they should
have buried 4 billion bodies, and many artefacts. If there were 10 million
people, it would mean 40 billion bodies buried in the Earth. If the evolutionary
timescale were correct, then we would expect the skeletons of the buried
bodies to be largely still present after 100,000 years, because many ordinary
bones claimed to be much older have been found.12 However, even if the
bodies had disintegrated, lots of artefacts should still be found.
Now the number of human fossils found is nothing like one would expect if this ‘Stone Age’ scenario were correct. The number found is more consistent with a ‘Stone Age’ of a few hundred years, which would have occurred after Babel.13 Many people groups could have used stone tools as they moved out from Babel (Genesis 11), having lost the technologies of metal smelting (Genesis 4:22) due to the Flood and the confusion of languages at Babel.
Immigrant peoples, when they settled in a new area, would have had an initial phase where they would shelter in caves, or have rudimentary housing. They would have made use of stone tools, for example, while they developed agricultural techniques appropriate to the local soils and climate, found sources of ores, and rediscovered how to manufacture tools, etc.
Groups that descended into animism might never emerge from this ‘stone age’ of their development, because of the stifling effects of such things as taboos, and fear of evil spirits. One tribal group in the Philippines, for example, had a taboo against water, causing rampant disease due to lack of hygiene—before the Gospel of Jesus Christ rescued them from superstition.
Australian Aborigines—how long have they
been in Australia?
When Europeans came to settle in Australia in 1788, it was estimated that
there were perhaps only 300,000 Aboriginal people.14 And yet today we
are told that the people have been here for 60,000 years or more. Now
there is no way that a mere 300,000 people had exhausted the plenty of
this large country so as to account for a long period of very low population
growth. If we allow for one-third of the land area as desert, it means
that there was only one person for every 18 square kilometres (7 square
miles) of habitable land area—hardly overpopulated, even for a subsistence
existence.
If 20 people had come to settle some time after the Flood, say 3,500 years ago, it would have needed a population growth of a mere 0.28% per year to produce 300,000 people. Such a minimal rate operating over 60,000 years could produce more people than there are atoms in the Milky Way Galaxy!
Australian Aborigines — cultural traditions
connect to Noah
In addition to population figures, there is much other evidence against
the supposed long ages of Aboriginal occupation of Australia—the
observed rapid deterioration of supposedly ancient paintings, for example.15
Furthermore, many Aboriginal tribes have stories, long predating their contact with Christian missionaries, of a global Flood, sometimes with startling similarities to the Bible’s account, but with sufficient differences to show that they were not recently incorporated into their folklore following contacts with missionaries.15 It is stretching credulity to suggest that these stories have been maintained by word-of-mouth for 40 to 60 thousand years, or that they were invented and just by chance have these incredible similarities to the Bible account.
The Aboriginal population and their stories are much more in line with their having been a nomadic/‘gypsy’ people who found themselves in Australia relatively recently—certainly after the Biblical Flood.
The real history of the world is recorded in the Bible,
the Word of the Creator-God who was there in the beginning. This record
shows that the world was deluged and destroyed (Genesis 6–9, 2 Peter
3) so that all people living today came from those who survived aboard
Noah’s Ark. A study of population growth clearly supports this Biblical
record.
