I'm sad to hear that, Vlatko...
Anyway, it's all about fairness. You can't see that all the people have the same things that support them in their life. For example, why does this guy live 60 years, while that one lived for only 13?? Why do some people live as princes while most of the people are poor people who can't earn their living??
Well, the answer is two-sided:
1- If you seek fairness, then it's illogical that this life was all what the poor guy has got. And knowing how life goes on in a very accurate way makes you think twice before saying that God is not fair, or there is no God at all. Of course, he didn't ignore fairness when he made all those great things in our lives. So, he will compensate for all those who had not all the factors in the Earth to live their live in a good way in another life.
2- If you seek fairness, and you think that universe was created by chance or by nature itself, then how could people get their compensation??
