Infinite regress: If God made everything, who made God?

The ancient Greeks, and Athenians wondered the same thing. They answered this question with the Logos.

The early Greek concept of Logos (λόγος) is one of the most profound and influential ideas in Western philosophy, religion, and science. Its meaning evolved dramatically from the 6th century BC onward, and it was used in very different (sometimes overlapping) ways by different thinkers. In everyday archaic and classical Greek, logos simply meant:

Word, speech, statement, or utterance
Account, explanation, or reason
Argument, rational principle, or discourse
Measure, proportion, or ratio (especially in mathematics)

It was the opposite of mythos (story, myth) logos implied something rational, ordered, and explainable.

Heraclitus is the first thinker to elevate Logos into a cosmic principle. For him, Logos is:

The universal rational order or law that governs the cosmos
The underlying structure behind the constant change and flux of the world. (“Everything flows”  panta rhei)
The hidden harmony that unites opposites (day/night, war/peace, life/death)
Something both immanent (present in everything) and transcendent (beyond ordinary understanding).

They knew that if time and space had a beginning, it would require the "cause" of this beginning to be outside of time and space all together. An uncaused cause. Something eternal that has no regress. This idea further developed by the later Hellenists and Stoics was thought to be a different kind of God than all the others previously worshipped or believed in. This wasn't a being descended of others like the Greek  gods. 
In John's gospel he begins with;
John 1:1-3
1 In the beginning was the Word (Logos), and the Word (Logos) was with God, and the Word (Logos) was God. 2 He was in the beginning with God. 3 All things were made through him, and without him was not any thing made that was made.

John in the 1st century AD is telling us that Jesus is the God that existed in Eternity, independent of our universe. That He is the uncaused cause that answers the infinite regress problem of philosophy. Now by itself this isn't evidence of anything more than a philosophical idea of John's about His Lord Jesus. 
The Greeks had been discussing it for 500 years already.

Here's the spectacular part. God answered this question 1800 years before that when He told Moses;
Exo 3:14
God said to Moses, "I AM WHO I AM." And he said, "Say this to the people of Israel: 'I AM has sent me to you.'"

"I am who I am". He just is. The necessary being, the uncaused cause. He gave us the answer to a question no one would ask for 1300 years. 

This is the part that blows my mind. One of the main people responsible for this line of inquiry in ancient Athens was Socrates. He said he got his idea from his personal God. A spirit that talked to him since he was a child. He called Him Daimonion. God was talking to the Greeks and preparing the Gentile world for the coming of Jesus Christ. He started talking to Socrates around the same time that He stopped speaking through Jewish prophets. I don't believe this is a coincidence. God has been preparing the world to understand, and accept the truth of Himself. 

The God revealed in the Bible is the answer to the infinite regress problem. There was no God before Him. There is none beside Him. There will be none after Him. HE JUST IS.
