Nicely stated. Very good! Now see if you replace The Big Bang Theory (which is also a great show btw) with God and see how the pieces fall exactly the same way.
Scientific laws that, when combined, are proof for the existence of God:
1. Cause and effect;
2. Complex universe;
3. Universal entropy.
3. Universal entropy. - we evolved from simpler lifeforms. Complex systems can form from less complex systems, or they can form from more complex into less complex. 3rd down.
It's impossible to make him understand! Though it's so easy to see that life forms evolve into things more complex! And so are also stars or planets. Not only life.
It's impossible to make him understand that entropy is linked to order and energy, not to complexity. That those two notions are NOT correlated.
How dense are you, anyway?
Cause and effect is law. Evolution is barely theory. Law trumps theory, because law is fact while theory is not necessarily fact, and may only be fiction.
Cause and effect is programming. Programming means that greater complexity brought lesser complexity into happening, even if it was through even lesser complexity.
The fact that entropy has to do with order and energy doesn't have anything to do with the fact that entropy is a reduction in complexity.
You need to get back to your studies.
