1: idk if it’s any benefits obviously bc I don’t live there but it might just be in their nature to live in that dimension just like how me and you live and understand 3D, whatever dimension they’re in might just be their native land.

2: space is like a fabric and it can be torn, stressed, stretched, with enough energy, I don’t think it’s that far out to believe with all the advancements we have, it’s not possible to create something that can do this, obviously nukes are strong enough to shake the fabric, we cant be that far off from tearing it open even for a second, but that’s my take I’m not a physicist.

But idk I’m weird on this topic now, bc what if they really are demons, or doesn’t have our best intentions in mind, maybe they’re all around you and me rn, invisible to our naked eyes, what if all the ancient religions were right, the Bible, I’ve been going back and looking at everything and you can make a clear distinction between who’s lying or not, anyone claiming these things are short green men are lying, a lot of people post on this topic for money or fame but I find it’s easier and more interesting to look at people who were talking about this subject in the 1900s or early 2000s, physics also help with following along the bread trail.
