Hi CrazyKazza! This is a really cool question! The atmosphere presses on the earth’s surface (and on our skin, from all sides) with a force of about 1 kilogram per 1×1 cm square!
All that air, the entire atmosphere, weighs about 5 million billion tons! Although like Rosie said, we don’t get crushed because all that weight is distributed evenly over the entire surface of the Earth.
