Leave it to the clever Greek investigator Eratosthenes to bring it all together with a calculation (and a remarkably accurate one!) about the diameter of the earth, and also the inclination of its axis of rotation to its orbital plane about the sun. Amazing! And later in Medieval Europe, the earth was thought to be flat. What happened? You'll want to check facts and read more on the geodesy ("roundness") of the earth, and a link is provided to the Wikipedia article on exactly that subject.
The Gupta Empire astronomers proved the earth was round by studying the moon during a lunar eclipse. They noticed that the earths shadow on the moon was round, meaning that the earth itself was round.
The ancient Greeks had worked out that the world was round by looking at the shadow that the Earth makes on the moon. Colombus knew it was round.
no the world has always been round. but it was believed that the earth was flat because pioneers never traveled far enough to know then some one was smart enough to realize the earth was round.
Round. Most people by the time of Columbus did not believe the Earth was flat, despite what some history books will tell you.
spanish explorers conquered what two native empires?
Its a truth as the earth is round.
You said they say is round & you live there.

that the earth is round just like what Magellan said ... `The church says the earth is flat, but I know that it is round, for I have seen the shadow on the moon, and I have more faith in a shadow than in the church"

he said the earth is not flat but round it rotates around the sun to make it day&night.
The Greek scientist who is credited with demonstrating that the Earth is round was Pythagoras. He believed that the Earth was a sphere based on observations of the shapes of celestial bodies like the moon during lunar eclipses.
He proved that the world was in fact round, not flat. He aldo proved that it was larger than everyone thought it was.
He has been killed and he died without being able to prove it.
umm: "The Earth is round"? ------------------------------------------------ The Earth is not round - it is an oblate spheroid. ---------------------------------------------------------------------------- A (slightly) oblate spheroid seems pretty "round" to me.
