>>826704We don't. Geologists claiming any kind of serious authority on the age of the Earth are full of shit. Some recently formed rock from a volcano was sent into a lab which "dated" it to be millions of years old. Different "dating methods" require fine-tuned constants requiring the making of certain assumptions. Was the ratio of Carbon 12 to Carbon 14 always constant throughout Earth's history?
It all depends precariously on the philosophy of Uniformitarianism.
>>826450I remember in school when they stressed how "rare" fossils are and how "long" it takes for them to form.
This is simply rationalizing after the fact about the age of the earth, is it not? It only takes a few hundred years for fossils to form; this is why we have human artifacts, like the bell of the ship Isabell Watson, buried in the rock.
>>826647Darwinian evolution is also not experimental science and therefore it cannot be disproven. It's natural history or philosophy. Also. Natural selection =/= Darwinian Evolution.
