Epistemology: the philosophy of knowledge gained from: faith. Catastrophism: points to disasters (floods, earthquakes, used to explain features of ea(cid:396)th(cid:859)s su(cid:396)fa(cid:272)es (cid:894)(cid:373)ou(cid:374)tai(cid:374)s, (cid:448)alle(cid:455)s(cid:895, used to a(cid:272)(cid:272)ou(cid:374)t fo(cid:396) (cid:858)odd(cid:859) fossils fou(cid:374)d i(cid:374) (cid:396)o(cid:272)ks, by linking them to a particular religious doctrine (christianity) Uniformitarianism (cid:862)the p(cid:396)ese(cid:374)t is the ke(cid:455) to the past(cid:863: theory that geological events in the past acted the way they do today.

If sediments over time solidified into rocks, 6000 years could not possibly have been enough time for them to form: therefore, the earth must be much older. Example: mount etna, 3000 meter volcano was formed by thousands of small eruptions over several million years, fossils in limestone under etna, therefore, the limestone must be older than the volcano.
