Earth is at the center of the universe
It was previously thought that the Earth was at the center of the universe. From a person on Earth, they would see the stars and planets moving. Naturally, being the young humans, they assumed that the Earth was at the center of the universe and everything moved around it. This formed the basis of the Roman Catholic Church believing that the Earth was at the center of the universe. Scientists such as Copernicus and Galileo theorized later on that the Earth was not at the center of the universe, but was revolving around the Sun. The scientists who did support this position were attacked and prosecuted by the Christian Church.
In the late 1900's and the early 2,000's, the Pope officially recognized that the Earth was revolving around the sun and expressed regret over how the church have acted against Galileo and other scientists.
