Because from our point of view, it looks like the Sun and Moon and stars rotate around the Earth when really they don't. From an observer's viewpoint, the Earth appears to be standing still.
It was not until the development of the modern tools of astronomy (mathematics, telescopes) that the movements of the Earth, rotation and revolution, were found to produce the observed motions in the sky.
Yes. Because from our point of view, it looks like the Sun and Moon and stars rotate around the Earth when really they don't.

In Ptolemy's time, during the Roman Empire, people thought that the Earth was at the centre of things because it did not seem to move, while all the other objects in the sky moved around the sky in different ways. This idea was incorporated into the scriptures, and because of that people felt discouraged from challenging it.
Ptolemy thought the Earth was the center of the Universe and his theory described how the sun, planets and stars all revolved around the Earth once each day.
To explain the fact that planets sometimes move "backwards" relative to the stars in our sky.
I don't know sorry):I'm trying to find out too for a school project
Ptolemy believed that the Earth was the center of our universe
The very center. he belived everything revolved around the earth.
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.
Ptolemy
Ptolemy's theory was incorrect because he believed the Earth was at the center of the universe and that the other planets and the Sun revolved around it. However, he was later corrected by, I believe, Copernicus (Ca-per-ni-kus) who stated the Sun was in the center of the universe and that the planets, including Earth, revolved around it.

Ptolemy placed the earth as stationary at the center of the universe. Aristarchus placed the sun at the center with earth rotating around it.
