Question

Why is it unlikely for stable life to develop over the first few hundred million years of Earth's history

Answer 1

Answer:

In simple words, there existed no living on Earth for the first few million years since the environment was unsuitable for life. The original atmosphere of the Earth had a lot of water vapor but practically little oxygen. Volcanic activity blasted substances into the atmosphere such as nitrogen, carbon dioxide, hydrogen, and water vapor, but no pure oxygenation.
