Lunar rocks are known for being older than most terrestrial rocks because they come from the Moon, which has not undergone the same extensive geological processes that Earth has, such as plate tectonics and significant erosion. The oldest lunar samples, collected during the Apollo missions, have been dated to about 4.4 billion years old. In contrast, many of the oldest rocks on Earth are significantly younger due to the dynamic and ever-changing nature of Earth's surface.

While basalt and anorthosite are types of rocks that can be found on both the Moon and Earth, they generally do not reach the same ages as the oldest lunar rocks. Natural glass can also form from volcanic activity or impact events on Earth, but it does not represent the ancient solid crust formation as distinctly as lunar rocks do. Thus, lunar rocks are specifically recognized for their age and origin, distinguishing them from terrestrial samples.
