This process happened billions of years ago, over a long period of time:
1. Gravitational Collapse: The nebula collapsed under its own gravity, pulling the dust and gas together.
2. Accretion: As the material clumped together, it formed smaller bodies called planetesimals. These planetesimals collided and stuck together, growing larger and larger.
3. Formation of Earth: Eventually, one of these growing planetesimals became what we know as Earth.
So, the Earth wasn't created by any one person or entity. It formed through a natural process of gravity, collisions, and time.
