Kinetic theory and gas molecules

    The kinetic theory states that the gas molecules are randomly colliding with each other and with the wall of the container with high speed.The area of each molecule is very less and as they are moving with high speed,they exert great force. since the pressure is force/area , the pressure should be very high and each gas molecules should be able to drill holes and escape.
    But this doesn't happen.Why?

    Their mass is much more less. Area scales with length2, mass with length3.

    Pressure is a macroscopic concept, which is not useful for atomic level interactions.
