HOWEVER this is an excellent time to review https://en.wikipedia.org/wiki/List_of_impact_structures_on_Earth https://en.wikipedia.org/wiki/List_of_impact_structures_on_E... in particular the S2 to S8 spherule beds found in South Africa (AKA "the big one(s)" or "we are less than dust in the eyes of the gods").
The universe is a big place with some big rocks in it. There are also some !!fun!! simulations of things like the Vredefort impact on YouTube.

Smaller, for sure, but very recent and large enough for "nuclear winter" type scenarios.
