Final answer:

The three most important events in the making of Earth are its initial formation, the creation of the atmosphere and oceans, and the emergence of life. These milestones transformed Earth from a lifeless sphere into a habitable world teeming with biodiversity.

Step-by-step explanation:

When considering the major events that have shaped Earth, three stand out due to their significant impact on the planet's development:

  1. Formation of the Earth: Earth formed approximately 4.5 to 4.6 billion years ago from a cloud of gas and dust. Initially molten, the planet lacked an atmosphere and oceans, setting the stage for the environment we know today.
  2. Creation of the Atmosphere and Oceans: Gradually, Earth cooled and developed an atmosphere. As the planet cooled further, water vapor condensed to form oceans, providing a critical component for life as we know it.
  3. Emergence of Life: The earliest forms of life, prokaryotes, evolved in Earth's primordial conditions. Life began to diversify, leading to a complex biosphere and influencing the planet's atmosphere and geological activity.

These events were instrumental in changing a barren rock into a dynamic planet with a hospitable climate, capable of supporting a wide array of life forms.
