Those are all examples of the argument that a god is necessary, which relies on gaps in our knowledge or understanding of the universe. It's a weak first step (it's not proof, after all), but it's one that most people find at least somewhat compelling. The less a person knows about physics or astronomy, the more likely they are to find it compelling. Coincidence?
As one of those laypersons who knows little about physics or astronomy, I take some interest in the argument. It doesn't lead to any of the gods that humans have invented (which, so far, appears to be all of them), but it does imply that perhaps there is a being --or a whole other universe of beings-- who create and experiment with universes as some kind of research. Or perhaps for entertainment, depending on how like us they are. This doesn't bode well for any hope of an eternal future, so I doubt the idea will catch on.
As for total solar eclipses being unique to Earth and its moon, I'd say it sure does seem like a coincidence. It's a better argument than "I saw Jesus on a piece of burnt toast," but I just don't see the relevance.
