Who created God
If God created the universe, who created God?
If there ever was a time when nothing at all existed, then there would be absolutely nothing today. Nothing plus nothing equals nothing.
Something has always existed
Since it is the case that something does now exist, one must logically conclude that something has existed always.
The question then becomes this. What is the “something” that has been in existence always?
The universe had a beginning because the laws of thermodynamics demand it: the universe is running down and it cannot have been running down forever, or it would have already run down.
Some have proposed one universe giving birth to another, but again, there cannot be an infinite series of such births and deaths, as each cycle must have less energy available than the last and if this had been happening for eternity, the death of everything would have already happened.
There must have been a beginning
The cause of the universe must have been non-material because if the cause was material / natural, it would be subject to the same laws of decay as the universe. That means it would have to have had a beginning itself and you have the same problem as cycles of births and deaths of universes. So the cause of the universe’s beginning must have been super-natural, i.e. non-material.
The cause must have been outside of space-matter-time.
Such a cause would not be subject to the law of decay and so would not have a beginning. Even the simplest single-celled life is stupendously complex and needs a minimum of over 400 different proteins to make the machines that are absolutely essential for life.
Matter is not eternal
The very fact that scientists attempt to assign an “age” to the universe is revealing within itself.
A non-material, spirit must have always existed. That non-material eternal something must be spirit in its essence.
The Scriptures identify that spirit as being God. “God is spirit?” (1 John 5:11–12) An uncreated, eternal Spirit Being. God was not created.
Deuteronomy 33:27 (KJV)
The eternal God is thy refuge, and underneath are the everlasting arms….
God is eternal and He has always existed
