Also casts doubt on markers discovered showing possible life on other planets. We missed a source of oxygen creation on our own planet. Who's to say there aren't other ways that both methane and carbon dioxide are present on other planets.

(I'm certain there's life on other planets. This just makes it less likely that a planets with all the signs is one of those planets)

Methane’s a lot more complex of a molecule to occur on its own though

Last article I read said of the three gasses, methane was the most common to occur without needing life to make it.
