The Moon is orbiting earth because of earth's gravity just like earth orbits the sun but why does it stay at a distance?? Why doesn't Gravity pull the moon towards us??

If you tie a weight on the end of string and twirl the string around your head you can feel the weight trying to fly away from you. But the string you're holding won't let it fly away. The result is the weight circles around your head.

The moon (..the weight..) moves through space with a certain speed. That speed is trying to throw the moon off into deep space. But at the same time Earth's gravity (..the string..) is trying to pull the moon down out of the sky. The two forces exactly cancel each other and the result is the moon neither flying off into space nor crashing down to Earth but going around and around it.

Moon Crashing Into Earth

Because the orbiting of the moon creates a centripetal force that counters the gravity (and actually excedes it very very slightly, which is why the moon is moving away from the earth at about 3-4 cm/year).

The Moon Moves Away From The Earth.

The moon is fairly at present going faraway from the Earth. it may take an extremely vast asteroid to hit the moon to bypass it even a splash. in line with probability then, it may be close to sufficient to be attracted quicker into the Earth. yet small area rocks will merely poke the Moon and it won't do something extreme. frequently, earth satellites slowly (very slowly) fall closer and closer in the direction of the Earth.

When you are cycling, somtimes you negotiate a curve by leaning on oneside.In this position, your centre gravity shifts and you should have been pulled down by the gravity.But you continue to ride without falling.Why?;the same reason applies here also.
When the moon is revolving around the earth,two forces are acting on the moon.One is the gravitational force of the earth acting towards the centre of the earth and a centrifugal force(any revolving body will have a force acting away from the centre about which it is revolving) acting away from the centre of the earth.Both will oppose each other.The centrifugal force which is equal and opposite prevents the gravitational force from pulling the moon towards it.

The Moon can;t crash on Earth because the Moon and Earth have a magnetic force that pushes and pulls together without letting go. The Moon doesn't just crash on Earth because it has an orbit that makes it circulate around Earth.
