Why don't you check out the actual definition of entropy and where the 1st and 2nd Laws of Thermodynamics come from.
Note that the 2nd Law is about the tendency for entropy increase - this tendency can be delayed such as in the activation energy for chemical reactions.
While you're at it try defining the total energy of the Universe (be it closed or open) - you'll find it is not really possible. Hence it is difficult to apply Thermodynamics to the entire Universe.
Also the laws (as currently stated) do NOT apply to the Big Bang unless you have a quantum theory of gravity. Otherwise it is just speculation.
