To be honest, I think that before humans and civilization would take way too long to provide an accurate description of. I think the best way would be to make a short summary of the time before human civilization (including hunter/gatherers) and then start on the first civilizations.

Hmm, somehow this idea sounds like an excellent beginning for a novel... maybe even a series... maybe even... films?! 

To take an excerpt from this wikipedia page:

"The age of the Earth is 4.54 ± 0.05 billion years (4.54 × 109 years ± 1%).This age is based on evidence from radiometric age dating of meteorite material and is consistent with the ages of the oldest-known terrestrial and lunar samples"

Which would be the age of the universe if today's scientists are to be believed.

Actually, it's believed that the age of the universe is around 14 billion years, give or take.

Current interpretations of astronomical observations indicate that the age of the universe is 13.75 ± 0.17 billion years,

However, this is rather debatable, because we assume that the universe has been expanding at the speed of light or faster, and the furthest objects we can see are 14 billion light-years away, so we say it is 14 billion years.

I was about to start correcting everyone else on their facts, but since this discussion is more about time than random trivia, I won't.

So... you just corrected my fact about the age of the Earth with the age of the universe? That's like me saying bananas are yellow, then you going no, oranges are orange!

Did you mean we assume that the universe has been expanding at the speed of light or slower?
