which best explains a primary reason for the inability of life to exist in earth’s early atmosphere?\nthere was insufficient energy from material collisions to change their density.\nhigh temperatures during precambrian time caused surface water evaporation.\nvolcanic eruptions and comet collisions added different gases to the atmosphere.\navailable oxygen was used to help create an ozone layer within earth’s atmosphere.

Answer

Brief Explanations:

Early Earth's atmosphere had little free - oxygen. Oxygen is crucial for most life forms for respiration. The available oxygen was used to form the ozone layer, leaving insufficient oxygen for life to exist. High temperatures and gas additions from volcanic eruptions and comet collisions are not the main reasons for the inability of life to exist. Insufficient energy from material collisions is also not the primary factor related to life - existence in the context of the atmosphere.

Answer:

Available oxygen was used to help create an ozone layer within Earth’s atmosphere.
