I get your point, but even still. The Niger-Congo family is probably relatively analogous to the Indo-European family (both in internal diversity, geographic spread, and association with the spread of pastoralism/agriculture), but even still you've got the very convoluted Afro-Asiatic family, Khoi-San languages, numerous language isolates, &c. &c. But in Europe you only have the Indo-European family and Basque.
