How can methane be created on Mars? It is a gas right, and it isn't that cold there?

Methane is CH4. Carbon from Carbon Dioxide (CO2) and Hydrogen from Water (H2O).

Stoichiometrically, CO2 + (2)H2O -> CH4 + (2)O2

The process is performed via the Sabatier Reaction, which someone else linked to.

It's a gas at STP here on Earth. It's a liquid when it's being used as a rocket fuel.
