Available Energy Decreases Over Time
There is less available energy today then there was yesterday.
The Second Law of Thermodynamics states that the entropy of an isolated system, such as the universe, that is not in equilibrium will tend to increase over time, approaching a maximum value at equilibrium. The Third Law of Thermodynamics states that as the temperature approaches absolute zero, the entropy of a system approaches a constant.
Fortunately for us, the temperature of the universe is not zero. It is moving that way each moment, but it is not there yet.
At some prior time, all the energy in the universe was available. Energy must have been created at some finite time in the past; otherwise we would have died long ago.
The logical conclusion is that an infinite Creator made the universe a finite time ago.
