The laws of thermodynamics describe the relationships between various forms of energy and how energy affects matter. The First Law of Thermodynamics states that energy cannot be created or destroyed, and the total quantity of energy in a closed system stays the same. To elaborate it more and applying on our Universe it says that matter can be neither created nor destroyed and that the amount of matter and energy in the Universe remains constant.
This law is already proved and tested and that why it is a law of physics, not a theory. Implications of this law are that the Universe could not have created itself, It must have been created in the past, and no further creating must be going on.
This is what exactly the Bible says in the book of Genesis, chapter 2 verses 1 and 2:
Genesis 2:1-2: Thus the heavens and the earth were finished, and all the host of them. And on the seventh day God finished his work that he had done, and he rested on the seventh day from all his work that he had done. ESV
Bible says, “Thus the heavens and the earth were finished, and all the host of them.” The original Hebrew word uses the past definite tense for the verb finished, showing an action completed in the past, never again to occur. The creation was finished once and for all. That is precisely what the 1st Law of Thermodynamics asserts that neither matter nor energy can be either created or destroyed and that the total quantity of energy in a closed system stays the same.
From a Biblical perspective, indeed, there is no “creation” ongoing today. It is finished. Although within the system that is this Universe, every second the process of creation is continuously running like new stars are forming old are dying but all happening within the system resources, by using one resource and transforming it into another.
