Why are there still wars in the World whereas countries have their definitive borders?

Because it's in the human nature !

Promiscuity. Too many people on Earth.
Make an experimentation, stuff 10 people in a tiny room, wait, and you'll see that at some point, they'll start to fight. No mater their level of education.
Another problem is the control of resources. If a country is missing resources (like water, food,..), and the neighbor has these resources, this creates a feeling of unfairness, of jealously, of envy.
Also not to forget the balance of power. If you show you are peaceful, this can be interpreted as being weak, and others will take the opportunity to abuse you. Show your muscles, take the initiative and you won't be bothered.

Because it's easier to start a War than to maintain peaceful relationships.
