Prior to the Cambrian Period, the earth had little Oxygen and a plethora of CO2.  Before that there was the Hadrean Earth when there was No atmosphere, NO ocean, and no solid crust.  The sun was at about 70% of its luminosity.  In about 10 billion years the sun's current luminosity should increase by 10% as it becomes a yellow giant. The earth will be toast.
