One of the points often raised by doubters of Evolution is the circular logic that can be used in dating: We know T. Rex is 100 million years old, because we find the fossils in rocks which are 100 million years old. And we know these rocks are 100 million years old, because they contain T. Rex fossils.

So basically it's assumed that if it's possible to use circular logic, that's what's being used?

To a certain extent, if the animal is found not to be quite so old, then it becomes difficult to make the case that the rocks are so very old.

That seems to rely on an assumption that the rocks in question are the oldest rocks there are.

Try to pay attention...circular logic, something you're intimately familiar with, is what's being debunked here.
