There is no such thing as a "last country on earth." The concept of "last" implies a specific order or sequence, which doesn't apply to countries.

It's important to remember that:

* Countries are not arranged in any specific order. They exist in different locations across the globe.

* The Earth is a sphere. There is no absolute "last" location on a sphere.

Perhaps you're thinking of a specific geographical location or a country that might be furthest from civilization? If you have something specific in mind, please tell me, and I can try to help you find the information you're looking for.
