But that's no different then saying we have a huge universe, with so many billions of galaxies, each containing so many billions of stars, each of which has an unknown number of planets orbiting it. With all 3 examples you still need advanced technology to make a leap with association to ufo sightings.
I think the first thing everyone should do, which you have (inadvertently) highlighted with your posts is we need to forget about opinions on origin from believers and sceptics alike. We don't know if any visiting ET has travelled 4 light years, 400,000 light years or popped over from one of the moons in our own solar system.
Making assumptions before we get started is what pigeon holes this subject into fringe elements.
Actually, it's not the same.
If you could possibly move between universes, the theory would be that you would go from one to another, but stay in the same relative spot. That would mean that the problem of finding where to go in a universe of billion of galaxies and trillions of planets is solved.
Furthermore, many times we see reports of UFO's the seem to appear and vanish at will. The ETH says that this must be because of a technology that was developed that is completely unrelated to the travel between stars. Thinking in terms of traveling between dimensions would say that we see that because of the travel technology. ETH requires two separate pieces of tech, multi-dimensional theory (MDT) only requires one.
ETH has the nagging problem of visiting a new planet with it's diseases that one might not have resistance to. MDT sidesteps that by suggesting that each dimension is close enough that it doesn't require entirely new bits of medicine.
In other words, we have one theory (ETH) that requires all kinds of supporting pieces of tech to be assumed and posited that, while might be possible someday (I won't say they are impossible), aren't within any form of logical possibility right now... the MDT requires only one bit of tech that is very much possible in theory and has been shown to sometimes seemingly happen in nature (for sub-atomic particles at least)...
