Aristotle thought the earth was at the center and the sun surrounded the earth.including the planets and moons.
He thought that all earthly matter was drawn to the centre of the Earth through natural motion, so a sphere was the most natural shape. He noticed that the shadow of the Earth was curved during lunar eclipses, and he noticed that travelling significant distances North or South allowed you to see different stars.
Aristotle did not believe that the Sun was at the center; he thought Earth was. Aristarchus, a Greek astronomer, is probably the earliest person we know of who supported a heliocentric solar system.
I believe that was Aristotle. This would be a geocentric universe. Galileo however, knew the universe was heliocentric and was persecuted for it.
Because during a lunar eclipse, Aristotle observed that the shape of the earth was round.
Aristotle developed a theory that the earth was the center of the universe, and all the planets were attached to it via fifty-five invisible spheres. The moon was close enough to be within the earth's realm, and as a result, possessed the ability to go through phases. He believed these spheres were made up of a substance he called Aether.

Aristotle
Most of Aristotle's ideas were disregarded by other scientists. His most famous theary was that the Earth was spherical and in the center of the universe.
He thought that all earthly matter was drawn to the centre of the Earth through natural motion, so a sphere was the most natural shape. He noticed that the shadow of the Earth was curved during lunar eclipses, and he noticed that travelling significant distances North or South allowed you to see different stars.
WHAT demonstrates that the Earth is spherical?!
The Earth is geoid THE EARTH IS SPHERICAL
Yes earth is a spherical (round), thousands of years ago people did not know that planet earth was round, they just thought it was flat so if they went to far they would fall of the edge! but nowadays because of spacetravel etc, we have seen planet earth and they have noticed it was a spherical planet. So yes it is.
The Earth was first thought to have been speculated as being spherical from the 6th Century BC, with the idea being developed and more widely accepted into the 3rd Century BC. Pythagoras was around during the 6th century BC, he may have first speculated the Earths spherical shapes, but no one knows for sure. Other Mathematicians and philosophers such as Herodotus, Plato and Aristotle also contributed to the idea following Pythagoras' time.
