Never underestimate the power of indoctrination of children, or of those with childish minds. This is what keeps the Climate Change deniers going and it's what keeps Islam and Christian Fundamentalism going, and many other doctrines that are based on superstition or fantasy. The scientific method is the answer. Nonsense like this Flat Earth business is easily disproved. Even cave men knew that the world was round by looking at lunar eclipses. Think, people, think.
