Obvously (to me) this would end all life on Earth from the debris that came flying in. The Chixilib impactor was 6 miles across and the entire atmoshphere of the Western Hemisphere was heated to 350F for several hours. Dozens of similar sized rocks raining down in a pattern like the break up of Shoemaker/Levy would just be too much. Not to mention bigger pieces and "dust".
I dimly recall somebody working this out in detail once and a significant percent of the Moon returns home, especially around the equator. We retained a significant amount of water but there isn't enough time left in our Sun to re-evolve complex life before the end. Large lava oceans would be visible for milenia.
May as well speculate on the fate of an armadillo on the track of an Indy race.
(Since you don't have armadillos where you live, as an anti-snake bite measure, armadillos jump about two feet up when startled. That also happens when they are confronted by on-coming cars. Puts them at about grill height.)
Bisquits and gravy in front of fat people have better odds of survival than life on Earth in this scenario, I'd say.
