The idea first came from Aristotle, the Great philosopher of the fourth century B.C. Aristotle was the first to theory that the earth was the center of the universe.
Aristotle divided the Universe into two spheres: one above the Moon and the second under it. This enabled him to explain why there is no problem to move objects on the ground and in the air whereas the stars are stable.
They believed in a heliocentric universe. This meaning that the earth was not the center of the universe, but that the sun was. However, many people , including the church, did not agree with this theory. Instead they believed in a geocentric universe. Plato and Aristotle believed in this theory.
"Geocentric".
Aristotle

Aristotle or perhaps Ptolemy?

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.
Aristotle if thats how you spell it :)

Aristotle was the first to develop a geocentric theory. But it is generally accepted that the Greek astronomer Ptolemy provided the most elaborated model of the geocentric view of the universe in which the Earth was the center. This idea lasted for centuries until the time of Copernicus.

The Ptolemaic theory (geocentric) put forth by Claudius Ptolemy (100-170 AD) was based partly on the work of Aristotle. It was replaced by the Copernican theory (heliocentric) beginning around 1400 AD.
The Aristotle helps us understand the philosophy and history of biology by the theory that it advances.
