Because it is based on faith of believing in a theory that can't be proved. Its the THEORY of Evolution, not a fact.
Evolution has not been proved and can't be proved by observation, hence it has to be believed on faith just as any other religion. I notice a theme by Evolutionist Religious Zealots that they can't seem to handle the truth.

"Because it is based on faith of believing in a theory that can't be proved..."

Aside from the fact that being a proponent of the theory of evolution entails more than the application of faith, there is also more than faith involved in religion.
