Excellent question! It was made round by the force of its own gravity. There is so much material in the body of the earth that it tends to collapse toward the shape of a sphere. Imagine all of earth's mass formed into the shape of a rod 500 miles in diameter. As soon as it is formed, the ends of the rod would collapse, and the center of the rod, bearing the incredible weight of both ends, would collapse and explode outward. Gravity would settle the jumble of material into a sphere or sphere-like shape.
Although nobody knows for sure who first made the discovery that the earth is round, Pythagoras is indeed regarded as being the first recorded person to make the claim that the earth is round.
This is not something "made up"; the year is related to Earth's orbit around the Sun. 1 year = one round of Earth around the Sun.
umm: "The Earth is round"? ------------------------------------------------ The Earth is not round - it is an oblate spheroid. ---------------------------------------------------------------------------- A (slightly) oblate spheroid seems pretty "round" to me.

The Earth never became round. It has always been round in shape since it was formed at the beginning of time.
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.
