Young-earth creation geologists have long held that most sedimentary strata resulted from waterborne deposits during Noah’s Flood.

However, although we can measure many things about a rock, we cannot directly measure its age.

For example, we can measure its mass, its volume, its colour, the minerals in it, their size and the way they are arranged.

And then, depending on the assumptions we make, we can obtain any date we like.

It may be surprising to learn that evolutionary geologists themselves will not accept a radiometric date unless they think it is correct—i.e. So, how do geologists know how to interpret their radiometric dates and what the ‘correct’ date should be?
