Yes, space rocks can be very dangerous to earth especially when they are close to us.
if the earth did not have an atmosphere, than many rocks from space would have striked the earth's surface by now.
Comets and asteroids are made of chunks of space rocks and dust. Meteorites are space rocks that are captured by the earth's gravity and fall to earth.
Some objects in outer space that can damage the earth could be the following: Asteroids Sun Particles Rocks from other planets Space bombs Fire Other objects flying around in space
Meteorites.
Comets are the rocks that hit the earth during formation of oceans...
Meteors are rocks from outer space that strike the Earth's atmosphere and are heated to incandescence (glowing heat) by friction. Most are completely vaporized, but some do fall to Earth.

Space rocks will have colided with the earth before Homo-Sapians exsisted so it is, unfortunatly, impossible to calculate. But it's happening all the time ... small ones, that is.
There's nothing special about it; they are just falling rocks. Of course, they are rocks that fall FROM SPACE, and the Earth is just sort of "in the way" as the rocks are falling around the Sun.
A lot of the debris close to earth will end up coming back to the planet eventually, most of it will burn up in the atmosphere. It's not really dangerous to us on earth, but will present some danger to things in space, particularly close to the earth as more space debris accumulates.
A geologist studies rocks, among other things related to the earth.
