They (creationism and Intelligent Design) are neither testable nor falsifiable, nor do they make any testable predictions.

How is evolution falsibiable? Can you give me scenario which would prove evolution to be false?

The finding of elephant remains comingled with dinosaur remains. Would you like more?

There are plenty of things which would falsify evolution and old-earth geology.

(1) Existence of chimeras, a combination of two or more features from separate genetic lines (or, rather, separate branches on the evolutionary tree)... winged horses, for example

(2) A "young" fossil naturally occuring in an older strata--try finding a bird, reptile, mammal in the Cambrian or Precambrian layers. You won't find any. Not even one.

(3) An older layer atop a younger layer will never happen in geology in absence of an overturned/recumbent fold.

On the other hand, there are plenty of things that evolution predicts.

(1) Existence of pseudogenes which, when activated, can develop into older characterstics. jennyp had a wonderful article with pictures where scientists were able to "trigger" teeth (molars and all) in birds. This is a very important one, since YEC should predict that there is no such thing as a pseudogene.

(2) Animal fossils will never straddle layers. I.E., a whale skeleton will never cross layers.

(3) Genes will not "skip" species in an evolutionary tree. For example, if Hyracotherium has a certain gene, and modern horse has that same genes, then all intermediates must have that gene as well.

I had about 5 examples in mind when I started writing this post, but they all went away...
