Atheist Bus Campaign

The atheist bus campaign was started in 2008 by a group of people in the United Kingdom who wanted to spread the message that it is okay not to believe in any religion. They put up advertisements on buses that said, "There's probably no God. Now stop worrying and enjoy your life." This message was meant to encourage people to stop worrying about what religion they should follow and live their lives without having to worry about making others happy. The campaign was a way of promoting the idea of atheism, which is the belief that there is no God, and that people don't have to follow any particular religion to be happy.
