Theory on our 3D Universe. Infinite?

I have a theory about this so-called infinite universe.
Us three-dimensional people move on Earth in two dimensions. To leave this earth we must move into the third dimension, like jumping, or flying in an air plane where we are no longer on Earth, but above it.
This has led me to think that if we can move "on" the universe in three dimensions, maybe to leave this universe we must move on to the fourth dimension?

The earth is 3d.
