They are growing in numbers. It says in the article and I read it in the French news: 7% of the population of Brazil believes the world is flat. That’s millions of people. But then if you take into consideration the billions that believe in an all powerful invisible being and a equally undetectable place or places everyone goes and lives after they die... It’s not hard to understand how several million people can be sold on the idea that the world Is flat and all science is a government/Illuminati conspiracy to maintain control of the population. Despite millions of years of evolution the Neanderthal genes are still often dominant in large segments of humanity.
