[Image: 840px-Oxygenation-atm-2.svg.png]

Graphical form of what Anomalocaris said.  From Wikipedia page on "Great Oxygenation Event".  Essentially, life started over 3 billion years ago (maybe 3.5ish?) but O2 certainly wasn't around until 2.5 bya at the earliest, and didn't reach today's levels until relatively recently in the geological timescale

(In the picture the red and green are the upper and lower bounds, respectively, of the estimated oxygen concentration)
How will we know, when the morning comes, we are still human? - 2D

Don't worry, my friend.  If this be the end, then so shall it be.
