Because from our point of view, it looks like the Sun and Moon and stars rotate around the Earth when really they don't. From an observer's viewpoint, the Earth appears to be standing still.
It was not until the development of the modern tools of astronomy (mathematics, telescopes) that the movements of the Earth, rotation and revolution, were found to produce the observed motions in the sky.
