That's pretty much the definition of organic when you apply it to this planet too. Organic, historically, was believed to be materials only produced by a 'life force', but the synthesis of urea in the 19th century pretty much out that definition by the wayside, Today organic means the chemistry of
carbon
Particularly carbon/hydrogen bonding. This includes materials containing, but not limited to, three of four of the most common elements in the universe (CHON).
The contemporary meaning of 'Organic' as natural is scientifically meaningless.
