a naturally occurring substance is one that can be randomized in between matter of existence for example: it is a substance you can create without knowing what it does so it occurs naturally. the synthetic substance is one of which a robot could relate to as it is a type of substance used within robotics and metallics of vehicles and other electrical equipment (synthetic meaning robotic) Firstly synthetic does not mean robotic. Look it up. Secondly I'm not convinced that the answer above would be right even if it was coherent. Naturally occurring denotes a substance that occurs in nature, in the right circumstances this can cover a wide variety of things. Synthetic substances are artificial or man made, generally for a specific purpose. Even some elements can be synthesized though these are incredibly unstable and thus not naturally occurring.
