The field lines are a representation of the magnitude and direction of the field over an illustrated area. The field also makes use of a certain force on objects which are electrically charged. Thus, we can say field lines never cross because the sum of two vectors can only have one direction (with the exception of the zero vector), Field lines are a visual representation of a mathematical construct, like a graph of a function. If they do, it implies that there are two directions for the electric field at that point. So the total field would only have one line going through the same point with a direction which was given by the sum of the two other directions. It is basically because of this; a vector field is a well-defined function, so it cannot have two different values at the same point.
