Why is the air pressure is low in higher altitudes?

Air pressure in higher altitude is low, because of earth gravity. Air pressure is higher in lower altitude, This is due to earth gravity only. Because earth is attracted high amount of air by this gravity. When the altitude increases the earth gravity gets low. That is why the air pressure in higher altitude is lower compared to air pressure in lower level of altitude. In a nutshell even the atmosphere is with us for these much year due to the gravity of earth only.
