Identify the main idea of the following text
Building on the discoveries and knowledge of civilizations in Egypt and Mesopotamia, among others, the Ancient Greeks developed a sophisticated philosophical and scientific culture. One of the key points of Ancient Greek philosophy was the role of reason and inquiry. It emphasized logic and championed the idea of impartial, rational observation of the natural world.
The Greeks made major contributions to math and science. We owe our basic ideas about geometry and the concept of mathematical proofs to ancient Greek mathematicians such as Pythagoras, Euclid, and Archimedes. Some of the first astronomical models were developed by Ancient Greeks trying to describe planetary movement, the Earth’s axis, and the heliocentric system—a model that places the Sun at the center of the solar system.
