First we apply a law of logic known as the law of the excluded middle, which states that a thing either IS or IS NOT.
If there were a time when nothing existed, then nothing would exist today. Something and nothing are mutually exclusive. Something cannot come out of nothing because nothing is always nothing.
Since something now exist, it follows that something existed before nothing and is independent of nothing.
Again, applying the law of the excluded middle, we ask if the something is material (matter) or non-material (spirit) in nature:
We now know that the universe began at a moment in time with a colossal burst of energy (Big Bang).
First Law of Thermodynamics: Energy cannot be created or destroyed; the total quantity of energy in the universe is always constant.
Second Law of Thermodynamics: As energy is transferred or transformed, more and more of it is wasted (unusable) and it gradually degrades into entropy (disorder). One universe giving birth to another universe cannot avoid the law because each cycle has less usable energy than the previous cycle.
Thus, the something is non-material (spirit), otherwise it would not exist because through eons of time it would have exhausted all usable energy.
Einstein's Theory of General Relativity, universally accepted as true, states that time is linked to matter and space and that time itself began concurrently with matter and space.
Since the something existed before both matter and time, it follows that the something is timeless.
EVEN IF all the atoms and sub-atomic particles in the universe came into existence by themselves from nothing, what is the probability that these random particles could arrange themselves in place, and hold themselves in place, to form our fine-tuned universe without any guiding intelligence and power?
The probability calculation is so incredibly large that it becomes infinite and nil.
If the probability of all the atoms and sub-atomic particles in the universe forming and maintaining the fine-tuned universe without intelligence and power is nil, then the something is infinitely intelligent and powerful.
The something = Spirit, Timeless, Infinitely Intelligent and Infinitely Powerful = GOD.
