The History of Life By: Rebekah Townley and Maggie McCann

Archeology is the study of past human life as revealed by preserved relics Any document that claims to be a work of history has to be put through three tests.

The Internal Test The internal test to see if the document is consistent throughout. Aristotle's dictum says to give the document the benefit of the doubt.

External test Tests to see if the document is consistent with other reliable historical documents Bible passes this test better than any other historical document of its time.

Tests to see if the document has a relatively short amount of time from copy to the original and a lot of copies made in that time. The bible passes this test better than any other historical document of its time

When a absence of historical documents happens dating of the artifacts can still be done by dendrochronology and radiometric dating If an object has a date or is mentioned in a reliable source of history It has a known age. Dendrochronology is more reliable than radiometric dating but it has to have a master tree ring pattern. To be accurate.

Relative dating and the principle of superposition Relative dating is not as reliable as other sources of dating but can still give an absolute age. The principle of superposition is when artifacts are found in rock or earth that is layered, the deeper layers hold older artifacts. The principle of superposition underlying assumption is that the layers were formed one at a time

Thanks for the good grade Mrs. Cornforth! This ends our presentation
