Let me help you with this question.
We know from Newton's Third law of Motion that Every action has an equal and opposite reaction. The fish swims in water, birds flying in the air and rocket propulsion work on this principle.
On a frictionless surface, if a person sneezes or blows air from his mouth, It causes movement of that person. Hence, pushing the air in one direction, a person moves in the other direction.
But walking is not possible on a frictionless surface because taking a step requires gripping the ground through friction. So, in this case, the foot usually stays in the same place while rest of the body moves.
