I would refrain from the usage of the term "push." There is no pushing involved.

Conservation of momentum is what causes the rocket to move forward. Exhaust at high velocity goes out the back. The momentum of the exhaust has to be balanced by the rocket momentum going forward.

Rocket engines operate on a very simple principle. They burn rocket fuel, which blasts out of the nozzle in the rear. This movement has the opposite reaction of pushing the rocket forwards, like a bullet shot from a gun also nudges the person holding the gun back a bit.
