The outgassings of the Earth was stripped away by solar winds

early in the history of the planet until a steady state was

established, the first atmosphere. Based on today's volcanic

evidence, this atmosphere would have contained 80% water vapor, 10%

carbon dioxide, 5 to 7% hydrogen-sulfur, and smaller amounts of

nitrogen, carbon monoxide, hydrogen, methane and inert gases.
