I am saying that becasue most fossils and the geologic column are
composed of sedimentary rock layers, that is, layers of sand and silt,
your proposed methodology is worthless.
But we do get layers of igneous rock with sedimentary rocks in between.
So if we find a fossil in a layer of sedimentary rock, and there's a layer of igneous rock above and below, we can date those two igneous layers. And if we find the lower one is 1.3 million years old, and the upper layer is 1.1 million years old, we can conclude that the middle layer of sedimentary rock is about 1.2 million years old.
And if that layer has a particular fossil that is only ever found in that one layer, then we know that any layer that has that fossil is also 1.2 million years old, even if there are no nearby igneous rock layers to date radiometrically.
Really not a difficult concept...
If somebody wants to know when a rock was formed....so what?
Rocks don't form, turn to sand, then sprinkle out over the land
like fairy dust encapsulating potential fossils in the mix.
And if I had claimed that they do, your point would be valid. But I never made that claim, so your point is irrelevant.
