Q: Where wast thou when I laid the foundations of the earth?
declare, if thou hast understanding.
A: For the invisible things of him from the creation of the world are clearly seen,
being understood by the things that are made, .....so that they are without excuse:
Job 38:4/Romans 1:20
"Lead in zircons from deep drill cores vs. shallow ones.

If the ages are thousands of years, there would not be expected to be much difference, which is the case."CMI
