Billions of years ago, Earth's atmosphere lacked free oxygen.
Scientists call this a highly toxic atmosphere.
<h3>What kind of atmosphere was present on Earth in early times?</h3>
In the atmosphere of the primitive Earth there was no oxygen (O2) and nitrogen (N2), the air being composed of gases such as
- methane (CH4)
- ammonia (NH3)
- hydrogen (H2)
- and water vapors (H2O).
With this information, we can conclude that Early Earth's atmosphere may have been as toxic as that of Venus today. Earth is the only planet that harbors life (as far as we know)
