Probably the most popular and easiest one is whatever's up with UAP/UFOs. Maybe it's little more than some psychological phenomena with folks, but even then, the commonalities in what's observed/experienced are pretty fascinating.
More mundane ones would be whatever led to the universe's existence, earliest origins of life in the universe, and what spurs the emergence of consciousness. Those fundamental mysteries at the center of living being, I suppose.
Commonalities imply a similar misinterpretation of similar phenomena across sightings. So it has to be stuff that is common around the world such as airplanes.
