Will the moon ever hit the earth?
No. Most likely not. Current scientific theories suggest that the moon was created around 4 billion years ago when a proto-planet smashed into the young earth. The resulting debris that was scattered into outerspace either fell to earth or coalesced into the moon. When the moon first formed it was about 16 times closer to the earth at the time and has been slowly moving further away. Current estimates are that it moves about 6 inches further away every year. So instead of hitting the earth, it will most likely someday be released from earth's gravitational hold and fly off into an unknown space destiny and away from earth for eternity.
