I’ve used links to articles in Wikipedia as much as possible because Wiki articles are refined over time with our understanding of the subjectmatter and are less subject to link-rot.

There is so much in this world that only makes sense in the light of Evolutionary Theory. Some of these layers are from the decomposition of sediment, others come from chemical precipitation, others from decaying organic matter, and others from volcanic lava.
The reason we can see the layers is because they were formed in different ways.

These reasons will work from the general to the specific.
Layers are laid down on top of each other, with the bottom layers laid down first and the top layers laid down last; therefore, the layers on the bottom are the oldest and the ones on the top are the youngest.
Also, suggestions for improvement on any items is welcome as this is a lot of material over a wide range of scientific fields, so I have certainly bungled some things here.
The process of permineralization, where mineral deposits form internal casts of organisms, provides us with a vast quantity of fossils that give us an idea of the different forms life has taken in the past.
You will never find a Neanderthal bone in the same stratum as a Tyrannosaurus rex bone.
Tyronnosaurus rexes weren’t alive at the same time; therefore, their stratum didn’t get laid down at the same time.
because science is about refining our understanding of the truth.The Theory of Evolution is strong enough that nearly half these examples could be disproved and the evidence would still be fairly overwhelming.
