Ptolemy
That was the general belief held in antiquity.
It wasn't a polish astronomer that suggested the earth was not the center of the universe.
Ptolemy was the Roman astronomer who incorrectly argued that Earth was the center of the universe in his geocentric model. His theories dominated Western thought for over a thousand years.
Copernicus was a polish astronomer that first formed the theory that the Earth was at the center of the universe.
The idea that the Earth was the center of the universe was adopted because of the writings of Ptolemy and Aristotle. This was a common belief until the 1700s.
Copernicus
Aristarchus was an ancient Greek astronomer who proposed that the Sun, not the Earth, was at the center of the solar system. He suggested a heliocentric model of the universe, where the Earth and other planets revolve around the Sun. This idea was revolutionary but was not widely accepted in his time.
Aristotle believed in a geocentric model of the universe, with Earth at the center and celestial bodies orbiting around it in concentric spheres. He also theorized that the universe was eternal and unchanging.
Though many accepted the geocentric model of the universe, it was designed by the famous astronomer Ptolemy.
HE was the first astronomer to figure out the earth wasn't the center of the universe the sin was it was the heliocentric theory
Claudius Ptolemy, an ancient Greek astronomer, proposed the geocentric model which placed Earth at the center of the universe. This model was widely accepted for over a millennium until the heliocentric model proposed by Copernicus gained more support.
