Many people say that Christopher Columbus's voyage in 1492 answered this question. However, Aristotle's studies proved something nearly 2000 years before Columbus. Aristotle had two arguments:
1) One about a total lunar eclipse Earth that cast a curved shadow on the moon, which he hence concluded that Earth would have to be spherical.
2) The other about the fact that a person who traveled north or south would be able to see new stars that hadn't been visible before. If Earth were flat, people would all be able to see the same stars. During a lunar eclipse Earth comes between the Sun and the moon and casts a shadow on the moon.
Actually he did no such thing.
