Although the concept of an eternal God may be hard to grasp, we can see that it makes sense.
If someone else had created God, that person would be the Creator.
as the Bible explains, God is the one who created all things. Furthermore, we know that the universe at one time did not exist. Genesis 1:1, 2
Where did it come from? Its Creator had to exist first. He also existed before there were any other intelligent beings, such as his only-begotten Son and the angels. Colossians 1:15
Clearly, then, he existed alone first. He could not have been created; nothing was in existence that could have created him.
Our own existence and that of the entire universe testifies to the existence of an eternal God.
The One who put our vast universe in motion, the One who established the laws to control it, must have always existed.
Only he could have breathed life into everything else.
