What world history? Most is made up if humans have been around for 200 K years. You have perhaps 190 K years of undocumented historical silence.
Overall, not constant. Even if you are right it would assume constant, not overall. He references 300 mil at the time of Christ! Did you see that?
...
The article lists the population at around 300 mil at the time of Christ resurrection. ''If there were 300 million people in the world at the time of Christ’s Resurrection,2'' His footnote is to the Encyclopedia Britannica. You ignored that.
Yeah, I saw it. I laughed at it and then ignored it, because it makes his math
even worse (if such a thing is possible).
If you do assume a global population of 300 million at the time of Christ (assuming death at circa 34 AD), and a 0.44/0.45% growth rate (i.e. a doubling ever 155 or 156 years) then the global population at the moment should be somewhere north of
2 quadrillion.
Look, with a doubling every 156 years you get:
34 AD: 300 million.
190 AD: 600 million
346 AD: 1.2 billion
502 AD: 2.4 billion
658 AD: 4.8 billion
814 AD: 9.6 billion (more than the current global population)
970 AD: 19.2 billion
1126 AD: 38.4 billion
1282 AD: 76.8 billion
1438 AD: 1.536 trillion
1594 AD: 3.072 trillion
1750 AD: 6.144 trillion
1906 AD: 1.228 quadrillion
Or, if we assume a global population of 300 million at AD 34 and extrapolate backwards every 156 years, you end up at 6500 years ago for your boat people.
There is nothing wrong with his math and you need to redo yours. The population was 6 bil around 1999-2000. Divide that number by 2 for approx 30-31 times and you are down to the approx number for Noah. 6 people. That works out to a overall doubling every 150 yrs which is growth at .46% assuming 4500 yrs ago. Batton is right in the ballpark for two different groups.
Sure, but if you use that math (6 billion people in the year 2000, halving every 156 years of so) then you end up with a global population of:
11 people in 2526 BC. Which is the same time as the Mohenjo-daro city was constructing collective housing for
5,000 people and the city had a population of about 20,000. In fact,
the whole Indus Valley civilisation apparently didn't notice a global flood was taking place.
1.4 million people in 128 AD. When the Roman Empire was at its peak of about 65 million people.
93.7 million in 1064, when the 1086 Domesday book gives the
taxable population of England and Wales (excluding the two largest cities, London and Winchester, and anything north of Carlisle and Newcastle) as 1.71 million.
3 billion in 1844, when global population estimates never passed 3 billion until 1959/1960.
He references an overall growth at around .46 and the numbers work out and now you produce empirical evidence based on anything from the present to justify a population of 7.5+ bil people given humans have been around 200 K years with a 10 K seed population. You can quibble about the numbers during the 1st century but you cannot about the math. From 1600 to 2020 you have an expontential doubling 4 times from 500 mil to 8 bil. You cannot extrapolate them numbers back 200 K years. You get far better results 4500 years.
For the majority of human history, until the onset of the industrial revolution, global population has waxed and waned. Human populations have not gone inexorably upwards, not even in comparatively recent history:
The 12th/13th century Mongol conquests probably shrank the global population by 5% over a period of 50 years;
The Black Death in the 14th century may have killed over 200 million people (circa 30% of the global population at the time);
The Spanish Flu outbreak from 1918 to 1920 maybe 50 to 100 million, 3-6% of the global population possibly more.
Human growth rates were generally very low prior to the industrial revolution. There were
periods of stronger growth, even exponential growth, but you simply cannot extrapolate these out. It just doesn't work for anything bar short timescales.
If you examine the math, or you examine history, neither bears out a conclusion that there were 8 people who stepped off a boat 4000 to 5000 years ago.
It boils my brain that you'd even countenance defending such nonsense.
