Answer:
Naturally, they chose to believe the former, as it was the simpler explanation. Another observation that supported geocentric theory was the apparent consistency in Venus' luminosity, which was interpreted to mean that it was the same distance from Earth at any given time.
These are:
the Earth is the center of the universe and it is stationary;
the planets, the Sun, and the stars revolve around the Earth;
the circle and the sphere are “perfect” shapes, so all motions in the sky should follow circular paths, which can be attributed to objects being attached to spherical shells;
Under the geocentric model, the Sun, Moon, stars, and planets all orbit Earth. ... First, from anywhere on Earth, the Sun appears to revolve around Earth once per day. While the Moon and the planets have their own motions, they also appear to revolve around Earth about once per day.
This introduced gravitation as the force which both kept the Earth and planets moving through the universe and also kept the atmosphere from flying away. The theory of gravity allowed scientists to rapidly construct a plausible heliocentric model for the Solar System
Over time, ancient astronomers became aware that some stars did not move like the rest, and began to understand that these too were planets. ... This gave rise to the Geocentric model of the universe, a now-defunct model that explained how the Sun, Moon, and firmament circled around our planet.

1) Naturally, they chose to believe the former, as it was the simpler explanation. Another observation that supported geocentric theory was the apparent consistency in Venus' luminosity, which was interpreted to mean that it was the same distance from Earth at any given time.
2) In the geocentric system, the Earth is considered to be the center of the solar system. The Moon, the planets, the Sun, and the stars all rotate around the Earth (which stays still), with uniform circular motion. They compose the heavens, which are considered to be ethereal and unchanging.
3) The geocentric model states that the Sun and the planets move around the Earth instead of the heliocentric model with the Sun in the center. ... Obviously the Earth orbits the Sun. Sure, the textbooks all say that the solar system is heliocentric.
4) This introduced gravitation as the force which both kept the Earth and planets moving through the universe and also kept the atmosphere from flying away. The theory of gravity allowed scientists to rapidly construct a plausible heliocentric model for the Solar System.
5) The geocentric model was eventually replaced by the heliocentric model. Copernican heliocentrism could remove Ptolemy's epicycles because the retrograde motion could be seen to be the result of the combination of Earth and planet movement and speeds. ... The Ptolemaic order of spheres from Earth outward is: Moon
