: I think that in recent times there's been a bit of a move away from the idea that oil is derived from organic life. Also, proposing that oil on Earth has a biological origin doesn't preclude there being other ways of deriving it. Further, some will no doubt see this as evidence of past life on those bodies. Nevertheless, oil on extraterrestrial bodies does support the idea of a non-biological origin. [[User:Philip J. Rayment|Philip J.
