Your premise is garbage. A few moments worth of searching:

Same reason soup is only eaten in Italy.
I mean that’s only on a technicality because you can only call it soup if it’s made in the Soupini region. It’s the same damn thing everywhere else.
They’re not really. In fact, UFO sightings are more evenly distributed across the world than tornado sightings.
Real question is, why are there no UFO’s ever seen from Disneyworld? Quite generous of UFO’s to respect designated no-fly zones.
Ufo sightings happen all over the world, but since that’s a fringe science at best or outright scam at worst, you don’t find any references in international mass media.
Once you search domestically in the respective language of a country, you’ll get your share of results.

However at least of the German UFO clubs seem to be perfectly reasonable:
In Germany, there seems to be an endless list of hobby clubs and nonprofit associations. The Association for UFO Research (GEP) is one of them. Their databank includes 140,000 entries, and 95% of them can be explained. Aside from satellites, strangely shaped balloons is one common answer, as well as weather phenomena and insects that zoom across photos. The remaining 5% “perhaps also have natural causes, which we just can’t explain yet,” Hans-Werner Peiniger, GEP’s head, told DW. Members of Germany’s UFO clubs — there are at least three — are not blind alien believers, Leipzig-based Fleischer said. They are rational, engineer types who use limited resources to analyze what curious sky watchers send them. The result, however, can be a great deal of information about what is happening above us. The really interesting cases “are a matter for the military,” Fleischer said. “They control the skies and have instruments and radar.”
“Of course we have a UFO sighting club. It keeps detailed and well-organised records and 95% of sightings have perfectly ordinary explanations.”
That’s some peak Germany right there. Amazing.
Meh. To achieve peak Germany you need to sprinkle in some homeopathy and naturism.
