Are octopuses originally from another planet?

Are octopuses originally from another planet? It sure seems so, doesn’t it? They are a very weird creature!
But just because they are weird doesn’t mean they’re from another planet! In reality they are related to several other Earth critters. They are a mullusc and belong to the class cephalopoda along with squids cuttlefish and nautiloids. So although they are very weird, they are definitely not from another planet.
However, in the sense that we are all made of stardust that came from some Supernova explosion somewhere in the universe, then we are all from another planet or star!
