It would not be helpful (unless you just happened to need a rock for something) because the earth is about 4.6 billion years old, and there is much older rock, so there is nothing particularly notable about one that is a million years old.

In certain special circumstances, it could be used to put an upper limit on the age of something. For example, a million year old rock that had been carved into the shape of a horse would mean that it had, necessarily, been carved less than a million years ago.

Finding a million year old rock can provide valuable information about the Earth's geological history, including past environmental conditions, climate patterns, and evolutionary processes. Studying these rocks can help scientists better understand how the planet has changed over time and make predictions about future changes.
