I don’t know how you call it in your language, but this weird “garden of children” similarity is weird.
@ZySoua makes sense
apparently these were invented in german-speaking places and then spread to the rest of the world, some languages took the german "Kindergarten" directly, like english, others translated it as their version of a "children's garden"
