Exactly, it's estimated that there are up to a billion asteroids in our solar system, of which an estimated 100 million are larger than 10 metres across and likely to cross Earth's orbit at some point.
It's also worthy to note that even a small asteroid (i.e. about the size of a house) is enough to destroy a city, and a larger one could wreak havoc globally, regardless of where it lands.
Also, to quote Bill Bryson, "the number of people who in the world who are actively searching for asteroids is fewer than the staff of a typical McDonalds. (It is somewhat higher now. But not much)."
And we couldn't do anything about it even if we detected an asteroid that was going to hit earth, as we don't have any rockets that could reach it in time. The Saturn V rockets were retired in the early '70s, we (as a species) now have no replacement that could even reach the moon.
