The Greek astronomer Ptolemy (Claudius Ptolemaeus 100-170 AD) based his geocentric theory on the work by Aristotle (384-322 BC) and Aristotle's student Plato.
Galileo and Copernicus were two of the scientists to disprove Ptolemy's geocentric theory of the universe. The Ptolemaic theory stated that the center was earth.
Ptolemaic-Aristotelian cosmology was a geocentric model of the universe developed by Ptolemy based on Aristotle's ideas. It proposed that the Earth was stationary at the center of the universe, with celestial bodies moving in perfect circular orbits around it. This model dominated Western astronomy until the heliocentric model proposed by Copernicus in the 16th century.
It sounds like your teacher was referring to the geocentric theory, which states that the Earth is at the center of the universe, with all other celestial bodies revolving around it. This theory was widely accepted in ancient times until the heliocentric model proposed by Copernicus.
The geocentric theory, which proposed that the Earth was the center of the universe, was supported by many ancient astronomers, including Claudius Ptolemy in the 2nd century AD. Ptolemy's geocentric model, known as the Ptolemaic system, successfully explained the movements of celestial bodies for centuries until it was eventually replaced by the heliocentric model proposed by Copernicus in the 16th century.

The Ptolemaic theory is an ancient geocentric model of the universe that posited Earth as the center of the universe with other celestial bodies moving around it. It was developed by the astronomer Ptolemy in the 2nd century AD and was widely accepted until the heliocentric model proposed by Copernicus in the 16th century.

The name is of the general theory where celestial objects revolve around the Earth is known as the Ptolemaic system.

Ptolemy was the first person to introduce the theory of a geocentric universe, a universe in which everything revolves around the earth itself. But in 1543, Nicolas Copernicus was the first person to introduce and prove the idea that the universe is heliocentric, a universe in which everything revolves around the sun.
The Ptolemaic system or the geocentric systemÊargues that the orbital center of the universe is the Earth. The system states that the moon, the other planets, the sun, andÊthe stars circled the Earth.
The geocentric theory was formulated by the ancient Greek astronomer Claudius Ptolemy in the 2nd century, known as the Ptolemaic model. It proposed that the Earth was at the center of the universe, with the Sun and other celestial bodies orbiting around it.

it is the theory that the earth is the stationary center of the universe, with the planets moving in an epicyclic orbits within surrounding concentric sphere. it is the easiest answer i can say

This model of the universe placed the Earth at the center of the universe
