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?
