Eli5: a question about fire

462 viewsChemistryOther

When fire is created. In which like methane and oxygen molecules in a burner they move around and when he give them a spark they gain energy and move faster and break apart. And hit each other and loose energy in friction and sound, but what is this saying that they create more energy than the energy required to start the reaction. I really don’t understand that

A spark can start a bonfire. The bonfire produces more energy than it took to create a spark. 

More energy was created, than it took to start the reaction.
