A series of 12 radiometric dates were obtained from carbon containing material. 4. These dates were established by a variety of radiometric dating techniques, including carbon-14. 5. Rocks from the Moon have been measured by radiometric dating techniques. 6. He leaned towards the idea of old earth creationism but questioned radiometric dating . 7.
