The BBC recently wrote about people who believe the Earth is flat:

On 24 December 1968, the crew of the Apollo 8 mission took a photo now known as Earthrise. To many, this beautiful blue sphere viewed from the moon’s orbit is a perfect visual summary of why it is right to strive to go into space.

Not to everybody though. There are people who say they think this image is fake - part of a worldwide conspiracy by space agencies, governments and scientists.

Welcome to the world of the flat-earther.

I wasn’t sure if that was still believed by some people today. Now I know that it is.
