Short Answer:The ancient Greeks discovered the shape of the Earth was round (sphere) 25 centuries ago.In 1687, Isaac Newton said the Earth was an oblate spheroid (slightly bulged at the equator) due to the centrifugal force from the Earth's rotation..Long Answer:More than 2400 years ago, the ancient Greeks knew the Earth was round, knew its size and knew it orbited the Sun.Aristarchus (310 BC -- 230 BC) of Samos is the first on record to have claimed the Earth went around the Sun, a claim which necessitates both the Earth and Sun being round.In the same era (240 BC) Eratosthenes of Alexandria calculated the Earth's circumference (hence radius) to an accuracy of a few percent, using the change in the angle of elevation of the noon Sun between Alexandria and a location that is now Aswan, Egypt.In 1687, Isaac Newton said the shape of Earth should be an oblate ellipsoid (also called oblate spheroid) instead of a sphere and that was confirmed by measurements of French mathematician and physicist Pierre Louis Maupertuis in 1736.

Im sorry, what? The scientist that coined the term eureka? It is said that Archimedes did, but he said it slightly differently, along the lines of "I have done it, finally!" in Greek.
mikołaj kopernik did it he is a famous scientist from Poland (real answer)
Its a truth as the earth is round.
You said they say is round & you live there.
Copernicus is the first in modern times, but he may have been basing his theory on the work of an earlier Greek Natural Philosopher. Galileo used a telescope and mathematics to prove Copernicus' hypothesis.
There have been at least 2 major theories about the Earth's structure. Earth has been said to be both round and flat.
