Do you really meant that? Are you a fixed species creationist? If so, do you also take the story of Noah and the ark seriously? How did Noah get several million species on the ark?
IOW, I'm not sure if you realize, but no modern "professional" creationists hold to a fixed species view. In fact most would be insulted by the assumption that they did. In fact the most conservative creationists ironically invoke the most prodigious and rapid evolution, because they need, in a young earth time frame, to get the millions of species alive today from the ten or twenty thousand "created kinds" that they manage to hypothetically cram into Noah's ark.
Now we are disputing the facts concerning Noah's ark. What is about all this you feel threatened by? Do you have very much invested in your desire that there is no God?
