If a piece of stone and paper are dropped from the same height, which will reach the ground first?

A piece of stone and a piece of paper are dropped from the same height, it is seem that the stone reaches the ground first. Since the acceleration due to gravity does not dropped on the mass of the body, the acceleration of the stone and that of the paper would be the same. So they should reach at the same time on the earth, but due to the resistance of air two bodies reach at different time on the earth. If there is no resistance of the air, they would fall at the same time.
