It was a common belief for thousands of years
that the earth was flat.
Then a handful of explorers
ventured out alone into the seas
and proved the people wrong.

One of the common arguments I get about belief in christianity is "how can so many people be wrong?" and my answer to that is just look at Nazi Germany. Millions were mesmerized by Hitler's eloquent speeches and followed him like a herd of sheep. Look at Islam today. Millions and millions of muslims exist all over the planet. There are over a BILLION followers of Hinduism. Throughout history many, many people believed in a certain mythology or other belief and it faded away after time. The ancient Egyptian culture and religion lasted for thousands of years. Just because millions of people believe something doesn't necessarily make it true.
