Ptolemy.
That the Earth is a center of the Universe. The root of this model is already in Timaeus by Plato where Timaeus describes it.
Aristotle believed that the universe was geocentric, with Earth at the center and celestial bodies moving in perfect circular orbits around it. He also thought that the universe was eternal and unchanging, consisting of a series of concentric spheres made of a quintessential fifth element, ether.
Nicolaus Copernicus, a Polish astronomer, proposed the heliocentric model in the 16th century, suggesting that the Sun is at the center of the universe with the Earth and other planets orbiting around it. This idea challenged the prevailing geocentric model, where Earth was considered the center of the universe.
The theory that the Earth was the center of the universe was popularized by Claudius Ptolemy, a Greek astronomer, in the 2nd century AD. This geocentric model of the universe was widely accepted in Western societies until the heliocentric model proposed by Nicolaus Copernicus in the 16th century.

Aristarchus of Samos thought that the sun was at the center of the universe and some "educated" greek people thought that the earth was the center of the universe but they were dead wrong because modern science now has evidence that the sun is the center of the universe.
The first scientist to say the earth is not the centre of the whole universe was Nicolaus Copernicus early in the sixteenth century.
This belief was known as the geocentric theory, which proposed that the Earth was the stationary center of the universe, with all celestial bodies revolving around it. This theory dominated scientific thought until the development of the heliocentric model by astronomers such as Copernicus and Galileo in the 16th century.
The invention of the telescope showed that the earth wasn't the center of the universe.
