4.6 billion years ago - most likely hydrogen (H2) and helium (He)
probably rich in hydrogen compounds like methane (CH4), ammonia (NH3), hydrogen cyanide (HCN), water (H2O), and formaldehyde (HCHO). Also some N2, CO2 but LITTLE or NO free oxygen.
Molecules of H2 and He move really fast, especially when warm, that they eventually all escaped Earth's gravity and drifted off into space.

<u>Fossil fuel- </u>The sources of fossil fuels are directly from the plants and animals, that are buried millions of years back and are converted into fossil now.
The consumption of fossil fuel leads to the emission of carbon into the atmosphere that is responsible for the increasing global temperature. This is one of the major problem of fossil fuel use.
<u>Nuclear fuel-</u> Nuclear fuels are derived from the radioactive elements such as uranium, strontium and potassium.
One of the major problem of using nuclear fuel is that it releases radioactive waste, that are harmful for various life forms.
<u>Renewable fuels-</u> This are renewable energy that can be generated again and again and are directly derived from the wind, water and the sun. For example, wind mill, solar panels and dams.
One problem of renewable fuels is that it has a lower production of energy such as electricity in comparison to the fossil fuels.
