Who is "our" do you mean your? Because Earth's early atmosphere was no where close to what we have today, while not as high a percentage of CO2 like Venus, it was pretty nasty from all the early out gassing of earth Earth. The reason why we don't have a CO2 dominant atmosphere today is due to water existing in a liquid state on the planet.To the best of our knowledge, the Earth has never had an atmosphere like Venus.
