Okay, let's stop ******* around, show me what Nasa says that disagrees with the OP or me, you haven't yet. Are you still on that "asteroids never hit the Earth" nonsense? Anyway put up or shut up about your NASA bullshit.
You should be aware that we aren't talking about the OP, oh he who can't think. I suggest you go back and reread this sub conversation before you make a complete idiot of yourself.
All that reply tells me is you can't come up with anything to back-up your NASA name-dropping. As you seem to be in the running for "Digitally Deprived Dimwit of the Month" award I did some work for you. Here's a few bits from NASA sites re:Asteroids (And I assure you these sites do
not claim Man never landed on the moon!)

NASA's "Asteroid Overview" site;
What do we do if we discover an Asteroid that may hit the Earth?
Although Hollywood has created some colorful methods for stopping an object that is on a collision path with Earth, no government agency, national or international, has been tasked or accepted the responsibility to stop such an asteroid, should one be discovered. But there have been a number of academic and some technical studies, not to mention numerous movies, on how a devastating asteroid impact might be avoided. Since asteroids outnumber comets 100 to 1 in the inner solar system, the asteroids, rather than comets, represent the majority of the nearer-term threat to our planet.
For the far more numerous asteroids that are smaller than a few hundred meters in diameter, if we have adequate early warning of several years to a decade, a weighted robotic spacecraft could be targeted to collide with the object, thereby modifying its velocity to nudge the trajectory just enough that the Earth impact would be avoided. The spacecraft navigation technology for impacting a small body was successfully demonstrated when the Deep Impact spacecraft purposely rammed comet Tempel 1 on July 4, 2005, to scientifically examine its composition.

Top 10 NASA Asteroid Factoids
1. Thanks to Asteroids ...
After the solar system formed about 4.6 billion years ago, comets and asteroids hitting Earth probably carried water and carbon-based materials -- the building blocks of life - to our young planet. Once life formed, later collisions, like the asteroid impact that killed off the dinosaurs 65 million years ago, altered the evolution process. This created an environment where only the most adaptable species, such as mammals, evolved further. We humans likely owe our existence and current position atop the animal food chain to these space rocks.
8. A Diverse Population
Asteroids were once thought to be whirling rocks in space but they are actually diverse in structure and composition. At one end of the spectrum are weak asteroids, ones that were once comets. These asteroids have either run out of ices to vaporize -- and lost their comet-like activity -- or have entered a dormant period where none of their ices are exposed to sunlight. These space rocks are highly porous and relatively fragile. Then we have asteroids that appear to be piles of rubble in terms of their structure. The Near-Earth Asteroid Rendezvous (NEAR) spacecraft's flyby of asteroid Mathilde in 1997 found this type of structure and so did Japan's Hayabusa spacecraft when it visited asteroid Itokawa in 2005. The NEAR spacecraft's rendezvous with asteroid Eros in 1999 to 2000 found a shattered rock structure, while the iron meteorites found around Arizona's Meteor Crater suggest that the impacting asteroid was solid nickel-iron. Talk about diversity!
