complex organic molecules that look strikingly similar to the goopy fossilized building blocks of oil and gas on Earth
Question for those who might know:

Would any organic molecules be essentially similar to the ones on Earth, just by the definition of the term; or would similarity in itself be an important thing to discover, as implying either a direct relation at some point (as in, organic molecules being seeded on both planets from space) or as telling us something about the likelihood that life elsewhere in the universe might be starting from similar points?

-- I hope that question makes sense; I'm not sure my level of knowledge is even good enough to phrase the question right.

(Of course, I don''t know what the authors mean by "strikingly similar", either.)
