In a way it does. If a theory contradicts the bible, then it is saying that what the bible says isn't true. So I can either disregard it, or I can say "Hey, your theory is interesting but I think something may be a little off because it doesn't mesh with the bible at all and contradicts what it says." But of course scientists won't do that. Therefore I am more interested in bible-friendly theories. And there are many Christian scientists who have theories, but they are simply just way less popular than the others.
