Energy can be changed from one form to another, but it cannot be created or destroyed. The total amount of energy and matter in the Universe remains constant, merely changing from one form to another.
Energy cannot be created or destroyed? This brings up the question of how the energy came to be in the first place. If you just say, 'It's been here forever' check the next law.
In all energy exchanges, if no energy enters or leaves the system, the potential energy of the state will always be less than that of the initial state
This is saying the things 'wear down'. A watch will run until the battery is out of charge, you will go down a hill until you run out of hill, etc. In every energy transfer, there is also wasted energy. Heat is a wasted energy, and I'll explain why in a moment.
The universe is constantly trying to balance itself out. A charge flow from a battery flows into a circuit because there is a voltage difference. Water moves because of a pressure difference. Heat transfers because of a temperature difference. These difference make things move, let us exist, and keep the world in check.
So if heat is always moving ( and it moves from hot to cold ) why hasn't the entire universe become a uniform temperature? The answer is that the universe has not existed forever, and the universe is still 'balancing itself out'. Eventually, the universe would become a uniform temperature, it would reach its equilribium.
So, if the universe has not existed forever, and it couldn't have created itself, ( due to its laws ) it must have been created from an outside source.
Our creator loves us, and he left us the story of creation in his Word, the Bible. If you have never read the Bible before, you really should do so! The Bible has brought love, peace, and joy wherever it is accepted. ( By the way, what are the three things that man continually seeks? Peace, love, and joy. We long for those three things )

My sister's taking that and loves it! Incidentally, she's doing the Dr. Wile book Exploring Creation with Physics. I think I'd like to do that :)

Actually, this came from physics! And yes, I love physics!

Hmm.. good stuff! This sounds like chemistry. Am I right? It reminds me of my Chemistry book by a Christian scientist called "Exploring Creation with Chemistry". The author is Dr. J. L. Wile. He's not Catholic, for your info, and he makes chemistry a breeze! He also points out certain things that we learn through our world that prove the existence of God, though this is not one of them. Interesting thoughts, though! I thought about your point too when I took that course. Are you enjoying chemistry?
