The fall is something that science does not take into consideration at all. We know that cold sucks the energy out of hot, the universe goes from order to disorder or entropy.
Sorry, but science absolutely does take the law of increasing entropy (disorder) into account. It knows all about how hot objects lose energy to cold objects, and how this causes a net increase in the entropy of the universe (second law of thermodynamics).
But although the universe as a whole is increasing in entropy, in disorder, that does not mean every spot of the universe is increasing in entropy. The earth, for instance, is an open system with heat flow from the sun and discharge of waste heat to the surrounding universe. The net effect of this causes a decrease in entropy of the earth, which can be used to drive all sorts of processes on earth.
And no, "the fall" is not where the second law began. The law of entropy drives all the processes of the universe, and this was going on long before people existed. Ken Ham, for instance, lists this argument about entropy beginning at the fall as so bad, creationists should never use it. I suppose that message didn't get down to the troops. See
https://answersingenesis.org/creationism/arguments-to-avoid/ .
This in and of itself is an argument for God because the universe is required to have an outside force in order for it to work.
We do not know that the energy comes from the God of the Bible. But we do know that the system requires an energy outside of the system.
Change that story to past tense, please. We know that the universe
required a source of energy to get started. Once it got started, it has no need for energy to keep going (although it is possible that dark energy is still being added to the universe.) And how the universe got its original burst of energy is a different topic for a different thread. Stay with the topic, please.
We have to build a house the house does not build itself. Then once the house is built it starts to decay. The atoms themselves do not have perfect bonds and they tend to fall about.
Not all houses are falling down. Some houses are being built. A good builder can build a house, even though the forces of nature lead to decay. Likewise, the laws of nature are quite good at using the natural forces of nature to build things that have order.
