I'll propose a kind of answer to this, and anyone who disagrees is welcome to say so.

Creationists' best arguments for creation are the "apparent design" in the natural world, and the Bible. Most anything else they say seems to attempt to explain why evolution is "wrong.," thus setting up a false dichotomy seeming to say that because one is wrong, the other must necessarily be right.

However, the Bible's testimony is rendered unreliable by independent evidence; and the conjecture of a designer to explain the appearance of design is enormously contradicted by a vast weight of evidence from many different scientific fields. So neither of the creationists' two best pieces of evidence amounts to anything. The appearance of design in nature is better explained by a natural process that results in the appearance of design -- a process we have abundant, independent evidence for.
