Your third option is, of course, terrestrial. The biggest problem here is that if you restrict yourself to explanations other than terrestrial, you
have to invoke issues which are beyond the realm of science as we know it. If they are extra-terrestrial, you have to explain how they got here in a
universe where the speed of light is a real limitation. If inter-dimensional, you have to explain just how those multiple dimensions work. Right now
we don't have an acceptable theory. It's all speculation. I'm not saying any of this is inherently impossible. Maybe there is a way to get to warp
speeds and exceed the speed of light in ways that are practical for traveling. But speculation and science fiction do not make it so. We lack the
theoretical framework to show how you could do this.
The inter-dimensional hypothesis suffers from the same thing. And String Theory doesn't cut it. Intuitively many people feel the inter-dimensional
theory is true. Religions are based on it, but even if it is true, that doesn't mean UFOs come from there. The inter-dimensional theory is used as a
kind of excuse because the extra-terrestrial theory has the speed of light problem. There's no real correlation.
Once you get beyond science you have anecdotes and speculation. Somebody says they have been abducted. you believe it. That's enough for you. Once you
get to this level, though, it's a wide-open field where anything you can think up in your imagination must be true. As we have repeatedly seen, it's
also a realm where deceit and charlatanism are common. You have both people who are intentionally deceptive and people who are wide-eyed believers in
anything that sounds good and resonates with them. You can't separate the wheat from the chaff here with any kind of certainty.
The vast majority of UFOs are clearly mis-perceptions. they are daylight disks or nocturnal lights in the sky and nothing to get particularly excited
about. People mistake clouds, planets, the Moon, and streetlights for UFOs all the time. And very likely there are terrestrial military craft out
there that look very strange. The military is on record snickering that such things as stealth aircraft have been reported as UFOs. Such
mis-identification is encouraged.
Take, for example, Greer's press conference in 2001. There were seventy hand-picked witnesses at the conference and/or the accompanying book. out of
seventy 22 actually saw something. The vast majority have been told stories, seen message traffic, or seen blips on a radar screen. In the final
analysis you have a Baker's Dozen that have actually seen something--out of seventy. It's hearsay evidence. And these guys are supposed to be the best
of the best. So when people say there are millions of reports, therefore it must be true, they're not taking into consideration the quality of the
reports. Most of the Project Blue Book reports, which I have seen and read in conjunction with the ATS Archival project, are a single sentence:
"Witness saw a distant light in the sky moving rapidly west to east."
Bottom Line is that we lack the theoretical framework to determine where UFOs come from. OP's declaration of space aliens versus inter-dimensional
leaves out the most likely explanation for almost all UFOs: Terrestrial. And the number of credible reports we have is a very small percentage of all
of them, with a great many relying on hearsay evidence, imagination, and speculation as "explanations" for what is going on. Add to that the number of
charlatans in the field and your sample size is rather small. The vast majority of "sightings" are daylight disks and nocturnal lights, which are
really nothing to get excited about. If you think you know the answer, you're guessing.
