Before I answer this question, I would like to make it clear that I personally do not care, and I think this question is useless and irrelevant. What difference would it make if Albert Einstein believed in God or not? This is really another issue of Christians respecting persons, which God says is sin. No one is converted to any belief based on what Einstein thought, and even if they did, that means they worship Einstein as if he is a foundational standard for belief in something. I write this article mostly so I can make this first opening statement, and so people can understand that pulling for a belief in a "god" from a man worshiped by humanists is a waste of time.
I want to know how God created this world.I am not interested in this or that phenomenon, in the spectrum of this or that element. I want to know His thoughts, the rest are details."

"My religion consists of a humble admiration of the
illimitable Superior Spirit who reveals Himselfin the slight details we are able to perceive with our frail and feeble mind."

I don't doubt for a second that Einstein believed in a "god" of some sort, but I can guarantee it wasn't the God of the Bible. Remember, almost all false religions believe in a "god" or "spirit" of some sort, but all those false gods are based on one's personal experiences and/or feelings and/or traditions, instead of revelation from the written Word of God. Einstein was wrapped up searching for a "god" that was bound to this universe and based on his own personal experiences of investigation, which means he first has his own presuppositions by which he would interpret everything he witnesses, despite the truth given to us in God's Word.
First, let's see what Einstein had to say about the One True Living God:
the Jewish religion, like all other religions, is an incarnation of the most childish superstitions. And the Jewish people to whom I gladly belong, and with whose mentality I have a deep affinity, have no different quality for me than all other people... I cannot see anything 'chosen' about them."
-Albert Einstein, The Einstein Theory of Relativity, MobileReference, 2009, ISBN: 9781607785668
The Lord God chose the Jewish people to be a light to all the other nations, but they turned away from God repeatedly throughout the Old Testament, very similar to how Einstein has turned from God. He had no belief in the Christian God of the Bible, nor in the infalliablility of His Word.
Imagine you are in a Bible study, and after reading that God set Israel as His chosen people, the man next to you says, "God's chosen people? That's ridiculous and stupid. I don't believe that; it's just a bunch of silly superstitions." Is that what a Bible-believing Christian would say? Someone who would say something like this has not humbled himself before Almighty God and the Lord Jesus Christ in repentance; a man who would say that WORSHIPS HIMSELF, as he believes his own reasoning processes the deciding factor of what is truth, rather than God being the source of all knowledge.
"It was, of course, a lie what you read about my religious convictions, a lie which is being systematically repeated.
I do not believe in a personal Godand I have never denied this but have expressed it clearly. If something is in me which can be called religious then it is the unbounded admiration for the structure of the world so far as our science can reveal it."
-Joseph Giovannoli, quoting Albert Einstein, The Biology of Belief, Rosetta Press Inc, 2000, p. 2, ISBN: 9780970813718; See also E. Christopher Reyes, In His Name, AuthorHouse, 2010, p. 39, ISBN: 9781452021492
Notice that he did not say he did not believe in a "god," he said he didn't believe in a PERSONAL God, which is the Christian God of the Bible, the Lord Jesus Christ. In fact, most false religions of the world, like Islam for example, believe in a pagan, impersonal god that cannot be known, which means so-called "revelation" of false religions is based arbitrarily on personal feelings.
In the eyes of Einstein, the limitations of existance were bound by scientific discovery, and since science cannot go beyond nature, the God Einstein believed in had to fit inside the universe. Again, Einstein believed in a limited false god stuck in a materialist box.
So in this grand (and sometimes vicious) debate on whether or not Albert Einstein believed in God, who is right? The atheists or the Christians?
I think both parties are foolishly trying to persuade the other that Einstein believed this or that, but the reality is that if you think Einstein is the grand decider of truth, as a Christian, you are breaking the first commandment by worshiping a false god called Albert, and as an atheist, you are openly contradicting yourself because you are worshiping a false god called Albert when you claim you don't believe in a god!
Albert Einstein is not going to convert anyone's heart to a particular worldview, and he is certainly is NOT going to save anyone from the wrath of God. Albert Einstein did not pay the penalty for mankind's sin on a blood-stained cross, nor is he currently sitting at the right hand of the Father, making intercession for the saints.
For the preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God. For it is written, I will destroy the wisdom of the wise, and will bring to nothing the understanding of the prudent. Where is the wise? where is the scribe? where is the disputer of this world? hath not God made foolish the wisdom of this world? For after that in the wisdom of God the world by wisdom knew not God, it pleased God by the foolishness of preaching to save them that believe.
-1 Corinthians 1:18-21
But God hath chosen the foolish things of the world to confound the wise; and God hath chosen the weak things of the world to confound the things which are mighty... That no flesh should glory in his presence.
-1 Corinthians 1:27-29
