I have two questions. Would or could we survive it or would it put us back to single cell amoebae crawling out of the seas?
And is there anyway to prevent them from crashing into us? Nuclear warheads
mounted on intercepting rockets. etc etc? KF :=(

What happens if an large Asteroid hits the earth?
We are All Doomed!?
Literally. I've been watching those same documentaries and have been for years. Even if a small asteroid were to hit, we are all doomed. What you see in the documentaries is exactly what will happen.
If they announce one is coming our way, best do what you've been wanting to do all your life. And, do it quickly!

I've watched these same "the sky is falling" documentaries. They all left me with the same impression.
Repurpose NASA (or use the UN) into an international group whose sole purpose is to research and test ways of protecting our planet from devastation by an asteroid or other stellar object and leave the business of space to private enterprise.
There are numerous proposals for diverting an asteroid from hitting Earth. Many of those proposals make sense. One has been posited by a former astronaut who so far has a stellar personal record. Quite a few, like blowing them up with nukes, will only make matters worse.
We should start testing some of these ideas on asteroids that pose no real threat to Earth. It's the only way to determine what method will be most effective. It'll also avoid lots of panic in scientific and political circles if we have a plan in place ahead of time.
To answer the OP question. I think such an event can be avoided if we're prepared for it. We survive it cause "it" never happens. If we do get hit we might still survive. Earth has survived at least a few devastating impacts and other natural events and life survived.
Honestly though I'm more concerned about things like Yellowstone erupting again, or the New Madrid seismic zone becoming active again.

These highly-trained individuals can usually be recognised by their distinctive superhero costume - invariably comprising a plain white vest.
Syzygy
To wit:
This extinction happened 380 million years ago in what is called the middle Devonian. It was a time when only small plants, wingless insects and spiders inhabited the land and everything else lived in the sea. About 40 percent of all species disappeared from the fossil record at this time. The extinction has been known to geologists for a long time but this is the first time it has been tied to a meteor strike. This is also the oldest known impact that has been tied to a mass extinction.
Only the cockroaches will survive.

The first one we can monitor and hopefully have some warning.
The second, well, let's just say bye to the south, New Orleans would be devistated, again, and most likely would not be rebuilt (plus over a dozen other major cities).
Oh, and to quote Bender:
DOOOOOOOOOOOOOOOOOOOOOOOOMED!

First, thanks for stretching the thread so far out sideways (not all of us visiting here have 25 inch monitors - perhaps you should consider that in the future!)
[space.com...]Astronomers Gear Up for Historic Asteroid Pass in 2029
During the early morning hours of April 13, 2029, observers in Asia and North Africa will have a chance to witness a rare celestial event as an asteroid, 99942 Apophis, passes within 20,000 miles of Earth.
Fedex has actually planned for such a contingency
Would I want to survive, assuming it was even possible? Are you kidding me? I'd prefer to be right underneath that thing when it hits. Give me 4 hours notice and a bottle of Jose Cuervo and, well, night, night...
New Orleans would barely feel the tremors as the core of the seismic zone is much farther north. Memphis and St. Louis are likely to be the hardest hit major cities. ;)
[neic.usgs.gov...]
That's a pretty big shake map, IMO.
Total destruction in New Orleans? Most likely not, but since nothing east of the Rockies is built for earthquakes, we can easily assume the damage will be much greater of a similar earthquake on the west coast.
You are looking at catastrophic damage in Memphis, major in St Louis and Knoxville along with noticeable damage in Chicago, Detroit, New Orleans, and Charleston. Most likely it will be felt in New York and parts of New England, too.
but in between we've got terrorists attacks
.....and then we've got concrete cases of nuclear waste in the oceans cracking open to give us radio-active fish.......cows being fed pills to stop them farting and burping causing us more diseases
.....landfill sites leaking toxic wastes into the surrounding grounds
....oil companies dumping toxic waste into rivers
Gee life sucks - I blame my parents!
I prefer to watch comedy and swill beer as it's much more relaxing than playing into the hands of the fear mongers that scare people for a living calling it "news".
I think the next big disaster is the reversal of the magnetic poles - which will happen in a couple of hundred years - read up on it.
We'll all be dead so reading about something I won't experience is a complete waste of time unless it's for sheer amusement value.
Kind of like living at 7,000 feet in the Sierra's and watching shows about tsunamis...
