Patently ignorant.
you cannot measure the age of a rock using radioactive dating because you were not present to measure the radioactive elements when the rock formed
and you if you were not present when a tree was a seedling, such as a redwood, for instance, you can determine its age to within a few months by counting the rings.
the fact that humans were not present when a rock was formed doesn't preclude determining its age by a number of methods. stratigraphy, for example. you need to go back to basic science classes. the bible is not a science book, by the way.
