The most predominant theory for the origin of the universe is the Big Bang Theory. All the energy and matter of the universe were condensed into a singularity that suddenly exploded spreading matter across the universe to eventually become the universe as it is today.
Without God, there are two significant problems with the theory, or any other origin of the universe. One being the existence of energy and matter. The other is what caused the singularity to explode.
Where did the initial energy and matter come from? Without God, neither can exist even in a singularity, since neither can create themselves from nothing.
According to science, something cannot come from nothing in a closed system, which includes the universe, without violating the first law of thermodynamics, one of the fundamental laws that govern the entire universe.
According to Khan Academy, the first law of thermodynamics is explained:
“The first law of thermodynamics thinks big: it deals with the total amount of energy in the universe, and in particular, it states that this total amount does not change. Put another way, the First Law of Thermodynamics states that energy cannot be created or destroyed. It can only change form or be transferred from one object to another.”
If energy cannot be created or destroyed, how is it possible to have no beginning where the universe has a beginning? That energy must have come from somewhere, since it still exists.
According to Las Cumbres Observatory , prior to the Big Bang:
“About 13.75 billion years ago, all of the contents and energy in the universe was contained in a singularity with infinite density and temperature.”
Just like energy being at the singularity, the matter was also there. Where did it come from without God? There is no way to even explain how a singularity came into existence without God.
In order to have the bang, you must have what precedes it. The universe cannot create itself, since nothing can create energy and energy was required for the Big Bang.
What caused the Big Bang?
According to CERN, the Big Bang was how:
“The universe began, scientists believe, with every speck of its energy jammed into a very tiny point. This extremely dense point exploded with unimaginable force, creating matter and propelling it outward to make the billions of galaxies of our vast universe. Astrophysicists dubbed this titanic explosion the Big Bang.”
There is no way to know how long it was condensed into a singularity, only that it is commonly believed that at some point, there was an explosion that caused everything to expand from there.
It had been sitting there for however many years without exploding and suddenly exploded. Why did it happen? It was clearly a stable singularity that suddenly became unstable, which should not have happened.
Without God, the energy and matter that existed at the beginning and the bang itself could have happened without violating the laws of physics. Laws cannot be violated under any circumstances.
It is only with God, as the creator of the universe, that explains the origin of the universe. As creator, God can add energy anytime God chooses. Just because man and nature are unable to create energy, does not mean God is limited by man and nature.
It is also only through God that a stable singularity could contain all the energy and matter in the universe to become unstable. With God, all things are possible, even when something is scientifically impossible, like energy being created and matter being created from nothing and explosion that spread that energy and matter throughout the universe.
God is not limited by the laws that govern the universe, but man is.
