I - Methane (CH4), ammonia (NH3), carbon dioxide (CO2), water vapor (H2O) and hydrogen (H2) were present in the Earth's atmosphere about 4 billion years ago.
II - The study of the oldest rocks in the Earth's crust indicates that the Earth's atmosphere was formed by oxygen (O2), nitrogen (N2), carbon dioxide (CO2), and water vapor (H2O) about 4 billion years ago.
III - The Earth's atmosphere about 4 billion years ago was composed mainly of oxygen (O2), nitrogen (N2), and carbon dioxide (CO2).
