Organic chemicals are not uncommon in space. They're just carbon-water reactions. Unfortunately, those phenomena observed in the midst of space are not well preserved, as the reserves of water in space to allow for such continued reactions is often transient or sparse.

But who knows, perhaps they're the byproduct of a chemical reaction in some strange organism? Is life, including sentient life, but a peculiar quality of some giant rock, surrounded by gases, orbiting some random ball of plasma, nursed in water from carbon? Surely, some type of self organizing structure has evolved beyond the confines of such a scenario.
