Answer:

Organisms began to photosynthesize.

The surface cooled, and water condensed

Ozone formed and blocked ultraviolet rays from the Sun

Step-by-step explanation:

When orgasms started to photosynthesize, they caused the great oxygenation event. This favored evolution of aerobic organisms on the surface of the earth.

When the earth cooled, water was able to exist in liquid form and settled so life could begin.

Ozone (largely formed during the oxygenation event) protected genetic material from damage by UV light hence life was able to evolve on the surface of the earth (like we get sunburns, without the Ozone it would be much worse / wouldn't live).
