Holy shit! I’ve been telling my family this for YEARS. I am 100% Not Joking. Alien Octopi. But their not Alien, they are the most Advanced Octopi we’ve never seen. Think about it, its Completly Possible for there to be huge caverns deep into the earth, under the oceans, that could have been cut off from the outside world for millions of years. If a population of octopi got trapped and managed to survive, they might have evolved to a higher intellect then the octopi We see., they(The octopi We have studied) are Masters of camouflage and mimicry with at least the intelligence of a Dog, that we can detect. …..To anything that lives in the ocean, our world ,above water is technically “outer space” to them. They dont have bones, so if the chose to explore “outer space”, they’d need a suit. One that compensates for their lack of bones, like an Exoskeleton. Any intelligent being would study what works best in that environment . Humans (2 arms 2 legs) Dominate the surface. Being from those depths, they will probably need some really good Sun glasses too. ….1 octopus + Exosuit+ Dark Shades = Alien Octopi (The Grey)
