I wouldn't doubt it. Just like in The Abyss. Plus a lot of UFO sightings are usually from navy ships reporting them coming from or going into the water. It's not too far fetched to believe sentient life spawned like us in a different environment. But if they did form in the ocean, they really wouldn't be aliens since they're native to Earth as well. Unless we consider them illegal aliens. But that's a whole 'nother thing.
