The scientist credited for his geocentric theory is Claudius Ptolemy. To arrive at this answer, you can follow these steps:
1. Start by understanding the meaning of the term "geocentric theory." Geocentric means "earth-centered," and in the context of astronomy, it refers to the belief that the Earth is at the center of the universe with all celestial bodies, including the Sun and the planets, revolving around it.
2. Next, familiarize yourself with the key scientists associated with heliocentrism (the opposite of geocentrism) and geocentrism theories. The main proponents of the geocentric theory were Claudius Ptolemy and Aristotle, while Nicolaus Copernicus, Galileo Galilei, and Johannes Kepler were proponents of the heliocentric theory.
3. Consider the time period in which these scientists lived. Claudius Ptolemy and Aristotle were ancient Greek astronomers who lived in the 2nd century AD and the 4th century BC, respectively. On the other hand, Copernicus, Galileo, and Kepler were prominent during the 16th and 17th centuries.
4. Based on the time period mentioned above, Claudius Ptolemy is the scientist credited with the geocentric theory.
Therefore, the correct answer is Claudius Ptolemy.
