Follow-on note, looking at a lot of posts contending these beings are demons etc. That's actually a lot more convincing to me than just space aliens. Again, the sheer distances involved with interstellar travel make this impossible. And, it looks as though the speed of light is the fastest speed you can go. Noting that most of the universe is hundreds if not thousands if not millions of light years away than why even bother. Worm holes seem to be the popular solution to this speed limit, but, no one seems to understand the sheer amount of energy that needs to be generated in order to create a worm hole. And then you have to get in and out and aim it too. Given all this, I think interdimensional beings are far more likely. This is the realm of demons and the like.
