I take that back, they do assert falsification criteria. And then, when some of the criteria has been met (such as age of the earth estimates), they handwave it away.

In other words, it can be "falsified" (their specific presentation of the theory), but they've already decided that it won't be falsified.

Mind you, they admit that the whole "God" issue is non-falsifiable, which means that "God" cannot be a part of the theory at all.

And furthermore, even if they accept the evidence regarding the age of the earth, all the need say is that God created it in such a way that the earth appeared to be older than it really is. This line of reasoning applies to any potential falsification criterion for creationism. That's why it's not science.
