It only sequences the age of things or determines if something is older or younger than other things.

When they put events in chronological order like they use Relative Dating.

With this in mind geologist have long known that the deeper a sedimentary rock layer is the older it is, but how old?

Although there might be some mineral differences due to the difference in source rock, most sedimentary rock deposited year after year look very similar to one another.

Estimates of the absolute age of prehistoric and geological events and remains amounted to little more than inspired guesswork, as there was no scientific basis for testing such proposals.” With this background, it is strange that the “standard geologic column” that identifies the rock strata on the earth and assigns very old ages to those strata was developed by Sir Charles Lyell in 1830.

This was done 100 years before absolute dating methods were available.

ANSWER: Relative dating is used to determine the relative ages of geologic strata, artifacts, historical events, etc.

This technique does not give specific ages to items.

Relative time places events or formations in order based on their position within the rock record relative to one another using six principles of relative dating.

Relative time can not determine the actual year a material was deposited or how long deposition lasted; it simply tell us which events came first.

This process lead to a system of time containing eons, eras, periods, and epochs all determined by their position in the rock record.

For example, rocks of the Phanerozoic eon are found on top of rocks from the Proterozoic eons therefore rocks of the Phanerozoic are younger than rocks of the Proterozoic.

We don't need to know what year any of these movies came out to place them in order of relative age.
