In each case, experiments can be performed to reveal the correctness of the system. In the heliocentric theory, the Earth rotates around the sun and this is a mechanism that is found throughout the rest of the universe. While those notions are totally discredited in the modern world, the terms "sunrise" and "sunset" still pay homage to them. They had no idea of what relative motion meant, or how Galilean relativity worked.
