It's just common sense:
1. The scientific community would not accept evolution unless it were soundly proved. As a theory, evolution (Darwin) is on par with plate tectonics and the Big Bang. If origins of species were not understood, science would say so, just as it does concerning black hole singularities, time before the Big Bang, and life on other planets. Science is not scheming against Christians.
2. Evolution has no baring on the existence of God, because He could easily have created a universe complex enough to allow evolution to proceed by natural law. The presence and manifestation of God in the universe are not nullified by evolution.
3. Almost everything is evolving according to natural law: from the expanding universe, to the death of stars, to the changing chemistry of the Earth's atmosphere. Is life the only thing that doesn't evolve by natural law -- requiring the continual "tinker toying" of God?
Evolution is a simple, elegant theory, supported by the vast majority of scientists, an extensive fossil record, genetics, geology, biology, microevolution (laboratory and natural), and of course, common sense.
