Proof is limited to alcohol and mathematics (and logic), as the saying goes. Tim is correct that for the history of life, what we have is lots of evidence for biological evolution, mass extinctions, age of the earth, etc. An article on "Scientific Proof" states:
“In truth, science can never establish ‘truth’ or ‘fact’ in the sense that a scientific statement can be made that is formally beyond question. All scientific statements and concepts are open to re-evaluation as new data is acquired and novel technologies emerge. ‘Proof’, then, is solely the realm of logic and mathematics.” (by Dr. Doug Theobald)
According to "The Extinction Files" there have been 23 extinction events since the Cambrian period, with 6 being major ones (last one was the KT boundary mass extinction of the dinosaurs about 65 million years ago). For all intents and purposes they are “proven” but not in a mathematical sense. There is a lot of evidence based on the fossil record.
