1) 4.5 billion years ago: Earth started forming from dust, gas, and rocks in space

2) Gravity pulled all this material together to make a big ball.

3) Earth was very hot at first, mostly molten (melted rock).

4) As Earth cooled, a crust (outer layer) formed.

5) Volcanoes erupted, releasing gases like carbon dioxide and water vapor.

6) Water from inside Earth came to the surface and formed oceans.

7) Over time, tiny life forms (like plankton) started to make oxygen.

8) As more plants and creatures appeared, Earth became more habitable.

9) Millions of years later, Earth became the planet we know today, with land, water, and life!

10) This is how Earth went from a hot ball of rock to the planet we live on now!
