World population is 6.7 billion people. If we start with the biblical number of 8 people who survived the Great Flood 4111 years ago, we get an average population growth rate of 0.5% per year. To avoid changes caused by modern technology and medicine, let's deduct the last 257 years and use only the world' population of 791,000 people in year 1750. This gives us an average growth rate of 0.3% per year. This conservative figure is less than the world growth rate of 1% per year over the past 1000 years. It is also less than the 0.8% growth rate in Africa and Asia and the 0.6% growth rate in Europe, over the past 250 years.
At this rate of 0.3% per year, if we start with just 2 people 10,000 years ago, the world population would grow to 20,000 billions. This is 3000 times higher than the current world population. If we were to start 20,000 years ago, the world population would grow to 2*10**26. That's a population density of 130 billion per square foot. Now imagine millions of years?

Your math is way off, and your logic is faulty.
Sharks are millions of years older than people, yet the world is certainly not overflowing with sharks, is it? Most populations of each species is in a balance with other species. Humans were like that, too, for many millenia. At the current time, humans are an infestation on the earth, overrunning territory and altering habitat at an alarming rate. I've been wondering how long it will be before we reach the limits, becasue a dieback to ancient levels will then take place, if not a total extinction of our species (a slightly different 'end of the world' scenario than the fundamentalists expect).
What kind of growth statistics do you apply to the years of the great plagues? Even the religious persecutions of so-called 'witches' 'heretics' 'heathens' and 'non-believers' by Christianity throughout the Dark Ages puts a crimp in your steady percentage growth figures.
Human populations have remained static or even declined for many thousands of years. Your (lack of) logic uses steady growth rates that apply only after mosquitoes were eradicated from large parts of the earth, germ theory accepted and antibiotics were discovered, and vaccines widely used for all major diseases. Why, until the 18th century, even long sea voyages were limited because of vitamin C deficiency disease (scurvy) so excess population died off, unable to move away from local famine, drought, death or disease.
Where do you get your data? I need to know so I NEVER go there!

Very interesting argument, but false. First of all, there have been times that there have been negative growth rates, like during plagues, wars and pestilence (famine). Even though Homo Sapiens appeared millions of years ago, that doesn't mean there were no other hominids since then, competing for food and resources. If you look at the population explosion in the last 100 years, you would think that humans have always been this prolific. But in reality, it is our recent ability to increase our life span and fight off disease that would have killed our ancestors much sooner. Penicillin and the wave of antibiotics that followed has made such a difference. And BTW, one of reasons Africa has such a low population growth (in some places), is because of such low health care. Infants are dying from pneumonia at rates that would appall a Westerner. When you factor in war, there are reasons that our population is not higher. Even though during the 20th century, there were 2 world wars with millions killed, there was still a major increase in the population, credit to antibiotics and health care.
I believe that there are factors that naturally keep the population down. Wars, infections and diseases, predators, and there will always be some way to check our population. We live in an ecosystem with all the implications attached. We might not want to believe it but it is true.

Improvements in technology have changed birth and death rates for humans. The last 250 years represent a phenomenal outlier in human population, growth, and life expectancy. Humans were scraping at replacement level growth for many millennia.

A. The biblical flood by no skill got here about international wide. B. the first proto-human recognized about 4.5 million years in the past ( in accordance to mitachondrial DNA) C. a lot of our ancestors shared problem-free antecedents. D. Of the finished style of human beings born, because Homo Sapiens Sapiens developed, 1/2 are nonetheless alive on the on the spot. that is because of cost of inhabitants strengthen.

Ah, but we cannot start with "the flood". The story of Noah's flood appears in a book that was written by fallible men and it has been (mis)translated countless times. At best, the story is an allegory about obedience to God.
You cannot apply scientific principles of math and evolution to a book that was written just about as subjectively as anything has ever been written. Science is NOT subjective.

To disprove your theory that the universe is only 6000 years old take a look at the closest galaxy Andromeda it is roughly 2.5 million light years away. The light your looking at from that galaxy took 2.5 million years to enter your eyes not 6000.

You cannot use the same rates for modern man, to estimate ancient man.
And there were many more than 791k people in 1750.
Estimates are just guesses and yours are off .

Good for you! The answer obviously, is "it isn't!".
Neither does the "experts" carbon dating make any sense, but they always use their "statements" to prove what they think, true or not.
There is some evidence that some of the earth may be older....there are a number of explanations for this. But not that the population started that long ago....you are right.
All you have to do is work backward from the birth of Christ to the beginning...that is how long mankind has been here...plus the years from Christ's birth to now. People work at trying to prove their own theories.....much easier to listen to what God says...it always proves true!

You're right, we should just ignore all scientific observation and base our understanding on a allegorical account
