Well, you can also have track inside ! Think of the board as a sandwich. There is two side per slice of bread. Therefore, you can have the simple sandwich: 1 slice of bread, 2 layers. There is also a sandwich with 2 slice of bread (separated by your favorite ham): 4 layers. Things like big-mac, with 3 slice of bread: 6 layers! and so on. Of course, the more layers, the more expensive to manufacture!!! Therefore, a manual routing with 4 layers is far better than autorouting with 6 layers!
