Methane occurs when anaerobic (no air) bacteria decompose organic material. In this reaction there is no oxygen to convert carbon containing molecules to CO2 so th reaction only goes to CH4 which can still be oxidized further. Natural gas is thought ot be the result of decomposition of this typ in the distant past.
