Carl Sagan explained in his 1977 Christmas Lectures that Earth's initial hydrogen-rich atmosphere was lost to space because Earth's gravity was too weak to hold onto the light hydrogen atoms, which could easily achieve escape velocity. This allowed the atmosphere to evolve into the second, more stable composition (rich in volcanic gases like CO2, methane, etc.) before oxygen became dominant.
