Scientists used radioactive dating to study the age of material from the moon and Earth.
Explanation: Radiometric dating of moon rocks (Apollo samples) and Earth rocks using isotope systems like uranium–lead and potassium–argon gives ages of about 4.5 billion years, showing they formed at roughly the same time. Other choices are incorrect because there are no fossils on the Moon and atmospheric cycles or gas composition don’t provide precise formation ages.
