Propaganda suggesting people have been lied to and that the earth is flat has been splashed across a park in Bromley.

Banners and graffiti were left by the pond in Crystal Palace Park on Sunday (September 2) morning.

One local resident who was walking by told News Shopper: “They are idiots. They can be quite militant. It’s scary how some people just completely mistrust science.

“What have they got to gain by faking everything? There are lots of paranoid people around.”

One of the posters is believed to read: “Earth is not a magical spinning ball with bendy water. Gravity has never been proven.”

The banner goes on to state photos suggesting the earth is round are fake.
