The earth is approximately 4600 million years old life has been on earth more or 500 million years Name two conditions that would have made living on the earth difficult in the first couple of million?

Answer 1

The Earth was not inhabitable for the first billion years because it was cooling off. When our solar system drifted from the Sagittarius Arm and was out in the open, the radiation from our sun was much more intense and life went crazy, i.e.: the Cambrian Era. There was also no oxygen until after plant life came about and produced it. Then animals and fungi emerged, thrived, and evolved.

Answer 2

During the early years of Earth, the planet experienced intense volcanic activity and frequent asteroid impacts, which would have made living conditions harsh due to constant upheavals and extreme environmental changes. Additionally, the lack of a stable atmosphere and the presence of toxic gases in the atmosphere would have made it difficult for life to thrive in the early stages of Earth's formation.
