For approximately the last two hundred years, this succession of fossils in sedimentary rock has been used to argue that the earth has undergone successive events.
Yet, you’ve heard the news: Earth is 4.6 billion years old. That corn cob found in an ancient Native American fire pit is 1,000 years old. Geologic age dating—assigning an age to materials—is an entire discipline of its own.
Indeed, the impeccable state of preservation of most fossils requires the animals and plants to have been very rapidly buried, virtually alive, by vast amounts of sediments before decay could destroy delicate details of their appearance and anatomy.
Thus, if most sedimentary rock layers were deposited rapidly over a radically short period of time, say in a catastrophic global flood, then the animals and plants buried and fossilized in those rock layers may well have all lived at about the same time and then have been rapidly buried progressively and sequentially.

Time in geological terms has been described in two different ways: relative time and absolute time.
