In olden times, people thought the earth was flat. One representation was even that of a tree-shape wherein heaven was an umbrella that encompassed it. It took men of courage, like Christopher Columbus, to prove that the earth is round.

To get an accurate picture of how the world looks like, we can now use an earth globe. An exact replica of the earth should also show items like the equator and the median line, and properly label countries and islands. It is also important to get an updated globe because many new countries have emerged in recent years.
