The earth's crust is made up of rock layers which have fossilized life forms in them.

What formed the rock layers and the fossils?

How rock layers form:
Rock that has formed through the deposition and solidification of sediment, especially sediment transported by water (rivers, lakes, and oceans), ice
(glaciers ), and wind.  Sedimentary rocks are often deposited in layers, and frequently contain fossils.

This website says:

"We don't exactly know how the earth itself formed, but the way it developed its layers is by the heaviest elements sinking to the bottom."

Some believe the layers represent ages of earth's history, with the older layers at the bottom, and the younger layers at the top.  So, there seems to be some disagreement as to whether the layers at the bottom were just heavier; or if those layers are older.

How fossils form:
A life form dies and becomes buried before its body completely decays.  Water seeps down through the layers of sediment and carries dissolved mineral deposits with it.  The water seeps into the pores of the life form and the mineral deposits begin to harden.  As the life form's body decays, the form of it is preserved by the hardened mineral deposits.  Also, some hard parts such as teeth may survive.

"And God said unto Noah, The end of all flesh is come before me; for the earth is filled with violence through them; and, behold, I will destroy them with the earth."
Genesis 6:13

"In the six hundredth year of Noah's life, in the second month, the seventeenth day of the month, the same day were all the fountains of the great deep broken up, and the windows of heaven were opened.
And the rain was upon the earth forty days and forty nights"
Genesis 7:11-12

19 "And the waters prevailed exceedingly upon the earth; and all the high hills, that were under the whole heaven, were covered.
20 Fifteen cubits upward did the waters prevail; and the mountains were covered.
21 ¶ And all flesh died that moved upon the earth, both of fowl, and of cattle, and of beast, and of every creeping thing that creepeth upon the earth, and every man:
22 All in whose nostrils was the breath of life, of all that was in the dry land, died.
23 And every living substance was destroyed which was upon the face of the ground, both man, and cattle, and the creeping things, and the fowl of the heaven; and they were destroyed from the earth: and Noah only remained alive, and they that were with him in the ark.
24 And the waters prevailed upon the earth an hundred and fifty days."
Genesis 7:19-24

There are two basic hypotheses given:
(A) The rock layers and the fossils were formed slowly through natural processes over long periods of time.
(B) The rock layers and fossils were formed quickly through a great catastrophic flood, in a fairly short amount of time.

If the uniformitarian hypothesis is true: 
a. Those layers should be uniform throughout the earth's crust, with the heavier rock strata on the bottom, and lighter rock strata at the top.
b. The second possibility would have the older rock strata at the bottom and the younger layers proceeding upward.  The fossils would then represent what lived during that time period.

If the castastrophic hypothesis is true: 
The fossils might be in order of their habitat, body density, and ability to survive during a catastrophic world-wide flood.

Either hypothesis might yield the same observable results.

Not all layers are represented

"For more than a hundred years the geologists of all countries have been cooperating in this endeavor and the total thickness of the stratified rocks now recognized would exceed 500,000 feet (95 miles) if all the beds were directly superposed.
C. O. Dunbar, Historical Geology, 2nd Edition, pgs. 9-10

Two-thirds of Earth’s land surface has only 5 or fewer of the 12 geologic periods in place . . . 80-85% of Earth’s land surface does not have even 3 geologic periods appearing in “correct” consecutive order.

“If there were a column of sediments deposited continuously since the formation of the earth, the entire history of the planet could be reconstructed.  Unfortunately no such column exists.”

Dating Rock Layers

Circular Reasoning is Used

On the very next page it says you date the fossil by the rock it is found in.

“The intelligent layman has long suspected circular reasoning in the use of
rocks to date fossils and fossils to date rocks.  The rocks do date the fossils, but the fossils date the rocks more accurately.”

Vast Fossil Graveyards

Fossil graveyards such as these found all over the world are evidence of massive catastrophic events.  Was it many catastrophes, or one world-wide flood?

Clam Fossils

The most common fossils in the world are petrified clams, there are trillions of them.  Almost every one of them have one thing in common, they were petrified closed.  Clams open up very quickly after they die.  This requires sudden, deep, burial.  

If not one worldwide catastrophe, could there have been a series of them over different periods of earth history, rather than just slow natural processes?  Should uniformitarian scientists rethink their position for the sake of good science?

There were two basic hypotheses we were considering:

(A) The rock layers and the fossils were formed slowly through natural processes over long periods of time.

(B) The rock layers and fossils were formed quickly through a catastrophic world-wide flood, in a fairly short amount of time.

The majority of scientific evidence seems to point to catastrophism, not slow natural processes.

If a life form dies, it will not usually turn into a fossil.  Road kill does not turn into a fossil on a regular basis.  That requires sudden, deep, burial.  The buffalo is becoming extinct, but they are not fossilizing unless they were to get buried by a landslide or something.

When you find a fossil in the dirt, all you

basically know is: It died!  The story you tell about the fossil will often have more to do with your worldview than it does about real science. 

Fossils do not come with labels on them telling you how old they are or when they died.  They also cannot usually tell you how they died.  The best explanation for the fossil record is the fossils were all buried suddenly and deeply by a great flood.
