No, Chuck77. These laws apply in all systems. Whether they are isolated or not.
The second law, for example, describes systems in equilibrium. The difference between isolated and open systems comes in where the distribution of energy is not uniform in localized places.
Your biggest mistake here is that you think that the earth is a closed system. It certainly is not. It's very open. Things like the sun constantly add energy to the earth and everything on it. Energy also escapes from the earth. The energy distribution is earth is not in equilibrium. Do you realize that everytime you eat, you add energy that comes from the sun? Definitely not an isolated system.
