    why don't we feel the atmospheric pressure although it is large ??

    We don't feel it because our bodies are pressing back with the same pressure

    we feel the atmospheric pressure in all directions and the net resultant force will be zero
    EXAMPLE :if we are in the normal position we feel the pressure in all directions and the net is zero
    if we are infront of the moving train outer atmospheric pressure is more than the pressure between train and us

    These are not quite right. There are two reasons/cases: first, your chest doesn't collapse because it is filled with atmospheric pressure air. Other parts don't collapse because water is largely incompressible.
