It's basically the theory that the earth is at the center of our cosmos rather than the sun.
The geocentric theory, which places the Earth at the center of the universe, was accepted in ancient times and supported by philosophers and astronomers like Ptolemy. This model consisted of concentric spheres for celestial bodies and aligned with many philosophical beliefs about humanity's significance. However, it was eventually replaced by the heliocentric model, which accurately described the solar system with the Sun at its center.
