The first man to theorize that the Earth was a sphere was the ancient Greek philosopher Pythagoras, around the 6th century BCE. He based his idea on observations of the moon and stars, noting that they appeared round and suggesting that Earth, too, must be spherical. Later, philosophers like Plato and Aristotle supported this notion with additional observations, such as the shape of the Earth’s shadow during lunar eclipses. This concept was further solidified by the work of astronomers like Eratosthenes, who calculated the Earth's circumference in the 3rd century BCE.

The first man to theorize that the Earth revolved around the sun was the Greek philosopher and mathematician, Aristarchus of Samos, in the 3rd century BCE. His heliocentric model of the solar system was largely ignored in favor of the geocentric model proposed by Ptolemy, until it was later revived by Copernicus in the 16th century.
The first known individual to theorize that the Earth is a sphere was the ancient Greek philosopher Pythagoras, around the 6th century BCE. He proposed this idea based on observations of the Moon and stars. Later, philosophers like Plato and Aristotle supported this view with additional evidence, including the shape of the Earth’s shadow on the Moon during lunar eclipses. The concept was further solidified by Eratosthenes in the 3rd century BCE, who calculated the Earth's circumference.
