Creation or Evolution?

People have been trying to find out where they came from for years, but no one has the ability to acknowledge that. Some people believe that humanity, the life, the Earth and the universe were created by God which is called Creation.
On the other hand, some other people believe in the theory of evolution that explains the formation of the Earth and human beings naturally. I think that a person cannot believe in the Evolution and Creation stories at the same time because it is logically incorrect. If a person believes that God created people, then how can this person defend the Evolution theory? There is a contradiction between these two beliefs. In my opinion, even though I have been taught the Evolution theory, Creation is more logical than the Evolution theory. I think that the Evolution theory fails to prove where the starting point is. 

I think that people should not spend too much time for discovering where we came from. Everyone has the right of choose whichever fits his/her believes. Instead of discussing whether Creation or the Evolution theory is right, we need to concentrate the future because we have already existed. What is the point of finding the formation or creation?
