I think the reason it is considered a separate continent is due a western centric view, and not geographically motivated. If you look at it, it's mostly where the white people originally lived.
Also, the EU includes some overseas territories which aren't in Europe like Saint Martin and the Canary Islands.
Quick edit; from Saint Martin to Réunion is 13.600 km, and both are in the EU :p.

Apparently Guam to US Virgin Islands is 9,509.97 miles, or a bit over 15k km. 😜
