Gravity- or for some things, magnetism.
Friction does not move things. Friction is the force that opposes motion between two objects that are touching. Not enough friction allows for things to move, depending on what kind of friction; the less force it has.
Friction can damage materials,slice,and make things move because when you touch, rub or move these things we create friction.
Move
Because rolling friction is usually less than sliding friction. A cart will move easier than a sled.
it makes things move without friction

Friction makes it harder to move things.
Friction is what holds, stops things from moving. if there was no friction then things would be on the move 24/7.
It enables us to move: without friction we would be in a permanent skid. It allows us to hold things: they would just slide away.
without friction most things become impossible.
Because you wouldn't be able to move about without it.
Move
Friction is important because without friction we would be sliding and slipping everywhere as friction slows down and stops things. Friction occurs when two things touch or make contact.
