Eratosthenes had many contributions : he was the first person to calculate the circumference of the earth he invented latitude and longitude he was the first person to prove earth was round he was the first to calculate the tilt of Earth's axis
No. Earth was known to be spherical long before Magellan was born. Neither Magellan nor Columbus set out to prove that Earth was round. They set out to find if a westward route to Asia was feasible.
Jean-Bernard-Leon Foucalt, in the 19th Century
Eratosthenes: Computed the diameter of the Earth (to within 6%) around 238 BC. Magellan (or at least his ship and a lot of his crew): sailed around the world.
Benjamin Franklin was the first person to prove that lightning is a form of electricity.
To circumnavigate and prove that earth was spherical most people don't get wht i say- I'm just a smart ass... i mean ... to travel around the world to prove its round :P lol x

Horizon observation: If you observe a ship sailing away, you will notice that its hull disappears before the top of the mast, indicating the curvature of the Earth. Satellites: Images from satellites show the Earth as a spherical shape. Space travel: Astronauts have viewed the Earth from space and confirmed its roundness.
the fact that the time of sunrise and sunset varies from place to place on the earth proves that the earth is not a flat disc. if the earth were flat all the places on the earth would have sunrise and sunset at the same time.

no because there is other people that we dont know about that did
Nobody has ever proven the earth to be flat... in fact, that notion has been dispelled time and time again.
