Because we are moving along with it and the speed is constant :)
It's like travelling on a plane- you only feel the take off and the moment of landing if everything is ok, so unless the Earth stops or takes off somewhere at a great speed we won't ever feel its movement.

You can't feel the earth revolve because you and everything els spins along with the earth at the same constant speed.
