The first organic molecules were probably very simple carbon-based molecules made of few atoms. These molecules then combined with other simple molecules to form more complex molecules. Over many years and probably trillions and trillions of chemical reactions, more complex molecules, and more stable molecules, formed.
The simplest organic molecules, hydrocarbons, contain only hydrogen atoms bonded to a carbon backbone. The carbon backbone ranges from one carbon atom in methane, or natural gas, to thousands of carbon atoms, such as in polyethylene, a commonly used plastic.
