Maybe, but it doesn't stop people from arguing with it when they don't want to accept what it is saying.

The Grand Canyon thread is a case in point. We've got evidence of what a flood-carved canyon looks like, features in the Grand Canyon which could not have been carved by a flood, land to the north and south of the canyon which is lower and where flood waters would have gravitated to, and cosmogenic and urianium dates which put the erosion of the Grand Canyon at millions of years old.

To most people, this does speak for itself. There are others who don't want to accept it, but they have not yet been able to explain why the above means that there was a global flood and that the Grand Canyon was carved by it.
