One of the clearest evidences for a worldwide Flood is the growth of Earth’s population throughout time. If there was no worldwide Flood, and if man has been on Earth for a million years as evolutionists assume, why is the population explosion only recently becoming a problem? In A.D. 1650, the world population was estimated to be 400 million; in 1800, it had grown to 850 million. By 1990, it reached 5 billion. Current analysis indicates that the world’s population is now doubling every 30 years.
