At this point, an unproven assertion, although many believe that methane may have occured inorganically. No proof of that has ever been presented.
“Theistic evolution” is simply nonsense from a double-minded person. God’s word states in over 100 places that all life reproduced after its own kind, thus no evolution. The discovery of the DNA code was the end of evolution babble from a scientific POV anyway. The DNA code specifically prevented evolution from spoiling God’s creation.
All hydrocarbons, including methane, are organic compounds.
Any number of experiments have been conducted to produce organic compounds abiotically, from conditions believed similar to early earth.
Methane itself has been found on many planets, moons & comets in our Solar System, as well as a planet on another sun.
Any suggestion that all of this methane was produced by some life form is far-fetched and unsupported by physical evidence.
The more likely sources are abiotic processes.

That would include many devout church leaders (Pope John Paul comes to mind), who likely would not appreciate your casting aspersions on their faithfulness.

The simple facts are that no individual ever naturally produced a viable offspring of some other species (laboratory cross-breading possibly excepted), or "kind".
However: every offspring from every parent is different in some small respects from its ancestors and descendants.
These small differences accumulate every generation, and over very long periods can lead to sub-populations which no longer interbreed.
Then scientists call them separate "species".

In fact, scientific studies have shown that every generation inherits a small number of more-or-less random genetic DNA mutations.
Over many generations, these "small numbers" accumulate and become "large numbers" -- many weeded out by natural selection, but a few contributing to evolutionary adaptations.
