Haha wei, human did not evolve from Monkey, Chimpanzee or Orangutan. We are simply "relatives" - we descended from similar ancestors, which were technically called "great apes".
Scientific evidences abound that support the common descend, so it's not really that much of a controversy as some may lead you to believe. In the scientific circle, there's almost no doubt about the validity of the common descend, and the theory of evolution in general. It's already as established as the other scientific theories you have learnt about - theory of relativity, newton's law of gravitation, kinetic theory of gas etc. The relationship between human and other apes are supported by evidences from genetics, morphology, archaeology, biochemistry etc.
If you are interested in the evolution of human and evolution in general, you can always refer to Wikipedia:
Evolution is not a matter of belief, it's a hard science.
