  2. The beginning After the big bang there was an immense amount of super heated gas left over. Over time gravity condensed this gas and after billions of years stars started to form.

  3. How Earth formed Once the sun formed there was still a massive amount of gas and dust orbing it. From this the dust condensed to form planets.
