Just like how oil is a natural part of the environment - if we weren't digging it out of the ground, it would eventually make its way out on its own, through tectonic activity - like in Alberta and Venezuela.
Expect the rates aren't the same. Sure, methane exists in nature, but if we're producing more of it than would naturally happen, there will be more of it in the atmosphere.
See what's wrong with that argument?
