The Bible teaches that God created only two people in the beginning – Adam and Eve. If we were to carefully study of the Bible, we would fine that “the beginning” was about 6,000 years ago according to the recorded genealogies in the Bible. Today, according to the census.org, the world population is about 7.5 billion people. Is 6,000 years enough time to produce all those people?
The answer is absolutely! According to most scientists, the world gains people at a rate of about 1% every year. That number includes the death count as well. That means that every year the population increases by about 86 million people So, I did the math. In 6,000 years, the total would be about 492 billion people which is way over the 7.5 billion people on record today. However, that is not the entire story. About 4,500 years ago, a worldwide flood wiped out the entire population of the world leaving only 8 people alive (Genesis 6-9; 1 Peter 3:20). Even so, the number would be well over the population we have today. While we can’t be certain of the rate of population change through the Bible days, we can still understand that it is definitely possible that two people could produce the amount of people we have today.
But let’s go further and look at the question from a different direction. According to evolution, the world is billions of years old and humans have been around for hundreds of thousands of years. If this were the case, how large could we expect the world population to be? Using the same math as above, there would be over 8.2 TRILLION people on earth today. That is a lot of people, and clearly not even close to the number we have today. “Where are all the people? And where is the evidence of the people who died? Even with the death, disease, and war killing many people, we could still ask such questions.
From God’s Word, we know that the earth (and universe) is about 6,000 years old. Of course, there was the flood where the population had to “start over.” By simply using mathematical calculation – from the population of the flood until today – we have a great estimate that the human population should be around what we have – at least pretty close. But with a long age scenario, the numbers are much larger and simply wrong! “That is unless they want to invoke a global catastrophe like a flood to reduce the entire population…oh wait…that comes from the Bible.”
