Because their borders usually follow natural features, e.g. rivers, coastlines, mountain ranges. Or because their borders were drawn as the result of battles.

Why? Do you think that they should all have the same shape? The world is not built that way. Country borders are rivers, seas, oceans, mountain ranges, and other things.

Borders in the past have most often been settled by armed conflict. For that reason, land borders tend to lie along defensible terrain features like rivers that need to be bridged or mountain ranges with few passes.

well, it started when all the earth's land mass was one giant piece, and an earthquake broke it up into todays continents and islands. for a clearer picture on this, watch the land before time, the great divide. then, wars, land contracts, etc. defined the exact borders for various countries.

your question makes very little to no sense. maybe it is because the earth is round and is separated by seas and oceans, and the countries are often divided by rivers and other land masses.
