First of all, lack of evidence for a thing's existence does not equal evidence that said thing never existed.

Using your logic, the fact that there are no unicorns that exist today is not evidence they never existed.

As Rush would say, this is using absurdity to expose the absurd.

Uh, what exactly is supposed to be wrong with that statement?

Way to ignore all the posts pointing out that you missed the many transitional forms, both in the fossil record and on the Earth today.

But if you'd rather argue semantics, it is not incumbent upon me to prove that there have never been any unicorns on Earth. IDers are the ones making claims that they can't back up with any hard science.

Evolution has evidence to back it up. ID has only feelings and wishful thinking.

Wrong on both counts. I know several people who have unicorns sitting on their book cases and knick-knack shelves.
