Well that is not necessarily true as was proven by our extra-solar visitor a few months back.

It came out of the sun and so was non-viewable until it went past. As you see it came in the solar system at an angle and slingshotted around the sun toward earth.
Me? I'd like to survive if there was any way at all possible to do so and see what happens afterward. The worst would be that I die and if I'm going to die and so is EVERYONE pain or starvation etc. is not any kind of real concern. And who knows, if I survive others would as well and maybe something more of life goes on.
I remember reading Lucifer's Hammer years ago which echoes this situation with smaller though multiple
It would be impossible to survive something that big. The one that killed the dinosaurs was less than 30 miles across. The one in this scenario is almost 800 miles across. The impact from that would be like putting the earth 10 miles away from the sun for 10 minutes.
“According to abundant geological evidence, an asteroid roughly 10 km (6 miles) across hit Earth about 65 million years ago. This impact made a huge explosion and a crater about 180 km (roughly 110 miles) across.”
This is from the Planetary Science Institute. It’s truly incredible the amount of damage something so small (6 miles across) can do at those speeds. I’ve seen estimates as large as 10 miles. Apparently, the light was so intense that any life close enough would have been instantly blinded. The heat admitted during impact burned impressions of dinosaurs into the nearby rocks as well. The toxic ash cloud reached Mongolia (other side of the planet) within 12 hours. Archaeologists discovered the larger dinosaurs died first because smaller dinosaurs bones are scattered around them, which means they were scavenging during the initial temperature increase that killed the larger ones.
Sorry for going on and on. I’ve just always thought this topic was really interesting, partly because it could happen again.
