One Plus One Equals Billions
Let us start in the beginning with one male and one female. Now let us assume that they marry and have children and that their children marry and have children and so on. And let us assume that the population doubles every 150 years. Therefore, after 150 years there will be four people, after another 150 years there will be eight people, after another 150 years there will be sixteen people, and so on. It should be noted that this growth rate is actually very conservative. In reality, even with disease, famines, and natural disasters, the world population currently doubles every 40 years or so.
After 32 doublings, which is only 4,800 years, the world population would have reached almost 8.6 billion. That’s 2 billion more than the current population of 6.5 billion people, which was recorded by the U.S. Census Bureau on March 1, 2006. This simple calculation shows that starting with Adam and Eve and assuming the conservative growth rate previously mentioned, the current population can be reached well within 6,000 years.
