Even the evolutionists can't agree on most of their prominent theories
Scientists are quibbling about the exact details of evolution. Very, very few disagree that evolution takes place, they're just discussing minor details. This is how healthy science works.
Why only one intelligent race?
Define "intelligent". And let me tell you, as a psychologist, it's more difficult to define than you might think.
Explain the evolution of flight, did some primitive creature learn to climb trees, and fall out so much that it developed wings so it wouldn't bust it's little ass?
No, that would be Lamarckism, a long-since-debunked theory. Scientists actually disagree on the origins of flight but, again, they are quibbling over the details, not discounting evolution itself.
I could shoot so many holes in your evolution theories that it's embarrassing, but I'm yet to have any one convince me of error in the Christian account of creation.
In other words, "I have nothing else to contribute but am unwilling to admit the fact".
