These are all from the same language family (the indo-european language family), so it's no wonder that there are still noticeable similarities in a word this fundamental even after thousands of years of divergence.

>non-European languages

"European" languages isn't a particularly good category, since europe has a wide range of languages that don't belong to the indo-european language family, such as basque and the uralic languages, of which there are too many to list in europe, but some notable ones include hungarian, finnish, and estonian.

For reference, the word for "no" in finnish is completely different: "ei", but it conjugates similarly to a verb, so it's "en/et/ei/emme/ette/eivät" depending on the person and number. In the very closely related estonian language this system has already eroded away and left only "ei", and in colloquial finnish a similar process is already underway and the "emme/eivät" forms have already disappeared.
