Geological time spans from the formation of the earth to the modern day, measured in the billions of years. These huge amounts of time can be difficult to grasp when we are used to measuring in terms of human lifetimes! On the chart below, the last 100 years of our history would be represented by a thin slice 1/50th of a pixel thick! We have even had to use two scales to fit this chart on the screen, with everything before the Paleozoic being measured in billions of years, and not millions.
