What environmental conditions made it possible for the first living organisms to exist on Earth?

There were three habitats in total:
1) Water. In water, life arose and developed for many millions of years. All living beings are made of water. According to the model of the origin of life, A.I. Oparin’s life originated in the ocean.
2) Ground-air. In the process of evolution, this habitat was mastered later than the aquatic one. The peculiarity is that there is an atmosphere. Plants and animals arose on the ground-air environment, which adapted to this environment.
3) Lithosphere. Living conditions in this habitat are limited. High temperature prevails, there is no oxygen and the earth has a high density.
