Which is the most accurate method of showing the entire surface of earth

A globe

Explanation:

When we use a globe we can very accurately represent the Earth, its curvature, and with a good scale and coordinate system for the geography. This can be done on a map to an extent but in order for us to put a spherical body on a flat surface, we need to make some changes. This is why on maps you see some parts of continents as larger than they really are.
