any underwater being that's somehow able to move on to land via technology would most likely be able to reach the stars
now of all the planets out there with massive oceans, literally hundreds of billions of them, somewhere somehow there's gotta be some highly intelligent octopus things. that's what my money would be on
that or really really tiny bacteria like creatures that operate on a nano/planck size and we'll never be able to see or deal with them if they have bad intentions for us
I mean games like stellaris and mass effect are great despite handwaving certain technologies (mass effect fields, ftl drives, wormholes) because they give you possibilities to think about
i really really hope we figure out how to talk to sperm whales. they seem so incredibly intelligent and apparently machine learning AI shit is making a lot of progress....
If anything when well done these games can show you different ways life could evolve. Dextro-amino vs levo-amino, silicon instead of carbon, machine learning and 'artificial' life etc
fun fact, if our galaxy or planet is threatened by an incoming event that we can track and predict (like a giant asteroid) it's theoretically possible to yeet our entire galaxy, planets and all, in whatever direction we want by building a giant mirror on one side of our sun
honestly moving our entire planet and sun to where we want to explore makes infinitely more sense than trying to cram our entire species into super expensive ships
We would never have to even leave our solar system to accomplish this
