The “push” theories don’t describe a force where the earth would be pushing us off the surface. Instead, they theorize that pressure is coming from all directions pushing us down to hold us against the earth. In those theories, the “attraction” we experience is a result of a graviational shadow... the earth blocks us from the pressure from one direction, so the pressure is no longer in equilibrium and we feel a pull in one direction.
The theories don’t work, but that is the idea behind them.
You're right--because those theories don't explain orbits.
