This theory of time being the fourth dimension is now outdated. From my rudimentary understanding it is at least being strongly debated amongst physicists.
I understand time to exist as a measurement of the relative movements and positions of objects in space. Time does not exist as a dimension separate to the position of the objects it is measuring.
In other words it is a scale that our 3D brains use to make sense of the cause and effects of the things around us that are interacting.
