Or better, anything can orbit gravitationally the lightest of objects (as long as things like electrostatic forces are not overwhelming it)
Anything with a velocity bigger than a certain velocity (not sure how this is called - orbital velocity) and smaller than the escape velocity can orbit something in space (in this case atmosphere is not a problem)
Orbit yes; but ring formation I imagine would require a delicate balance of forces to maintain equilibrium. Which would imply this ring is either very young or formed by an extraordinary coincidence or umm.. curated.
wtf do you really believe the best possible explanation for a phenomena you know barely anything about which isn't outside of physical possibility (merely a supposed low likelihood) is "alien design"? Really?
When theories were built that way we used to call it "religion" not "science". Alien attributions seem pretty much a modern sci-fi/fantasy religion to me.
