The Ptolemaic Model followed a geocentric model of the solar system.
This was then challenged by Nicolaus Copernicus, who claimed a heliocentric model which sparked an integral part of the Scientific Revolution called, the Copernican Revolution.
Copernicus' proposal was followed by the Tychonic Model, with attempted to compromise with the geo- and heliocentric models.
Then, Kepler improved by suggesting elliptical orbits.
The Copernican Revolution came to a close with further speculation from Galileo Galilei and Isaac newton
TL;DR Because they were wrong
The Copernican System was developed by Polish astronomer Nicolaus Copernicus in the 16th century. He proposed that the Sun, not the Earth, was at the center of the universe, which challenged the prevailing geocentric model of the universe.
what evidence did ptolemy have for the solar system
The Copernican system, which proposed that the Earth revolved around the Sun, was supported by astronomers like Nicolaus Copernicus, Johannes Kepler, and Galileo Galilei. However, it faced opposition from religious authorities, such as the Catholic Church, who adhered to the geocentric model of the universe.
The geocentric model of the solar system that was accepted for about 1,400 years was developed by Claudius Ptolemy, a Greco-Roman astronomer, in the 2nd century AD. In this model, Earth is positioned at the center of the universe, with the Sun, Moon, and planets orbiting around it. Ptolemy's system was widely influential and remained the dominant astronomical paradigm until the Copernican heliocentric model gained acceptance in the 16th century.
The difference between Ptolemy's and Copernicus's model was that, Ptolemy's model had the Earth in the middle of the Solar System, with all the other planets (including the Sun and the moons) revolving around it. In Copernicus's model, he had the Sun in the center of the Solar System.

Ask not what Ptolemy thinks of his solar system, but what his solar system thinks of Ptolemy.

Ptolemy and Copernicus' ideas about the universe are different from each other in the sense that Ptolemy thought that every celestial object as well as the sun and the moon orbited the Earth whereas Copernicus had the thought that all planets orbited the Sun, while the Moon orbited the Earth.
