Could there ever be a good Creationist sci-fi novel, lol?

What do you guys think? Is good sci-fi dependent on the world being older than 6,000-60,000 years old. Does sci-fi, to be truly effective, need to have deep time. C.S. Lewis's works, particularly Perelandra, sometimes stray close to creationism, but ultimately draw back. Practically all Catholic sci-fi accepts the ancient Earth\evolutionary "hypothesis". The only evangelical sci-fi authors who are even halfway decent are Stephen Lawhead (who accepts the theory of relativity, but is silent on evolution), Kathy Tyers (who will occasionally use evolution in her secular works, though I don't know whether she believes in evolutionary theory), and Chris Walley (who as far as I know does accept evolutionary theory, and definitely accepts an ancient Earth). I think it would probably be easier for an Old Earth Creationist to accept an ancient Earth than a young Earther, but that's just my opinion. Tell me what you think.

Note: I'm not trying to keep harping on the Christian theme, I just haven't had time to watch real (i.e. secular or Catholic) sci-fi, but only read crappy evangelical imitations lately. Ah, such is life.
