William Lane Craig says there are good reasons for thinking that He does.
This in and of itself is truly mysterious. Did God create the universe in accordance with inherent immutable laws of matter [mathematically or otherwise] or did He first create the laws of matter themselves? Just look at how extraordinarily complex the laws of matter can be. Mind-boggling mathematics that only a tiny few can really grasp. Couldn't an omniscient and omnipotent God have created a reality considerably less complex? Or did He have no real choice in the matter because of necessity these laws are by their very nature complex?(III) God is the best explanation of the applicability of mathematics to the physical world.
Okay, now connect the dots between this and a God, the God, your God.Philosophers and scientists have puzzled over what physicist Eugene Wigner called “the unreasonable effectiveness of mathematics.” How is it that a mathematical theorist like Peter Higgs can sit down at his desk and, by pouring over mathematical equations, predict the existence of a fundamental particle which, thirty years later, after investing millions of dollars and thousands of man-hours, experimentalists are finally able to detect?
Scientists will sometimes speak of the "God particle":
"The Higgs boson is often called 'the God particle' because it's said to be what caused the 'Big Bang that created our universe..." CBS news
So, perhaps one day scientists will prove the existence of a God, the God...mathematically?

Still, what are the chances that it will turn out be your God and not their God?
Yes, all of this is truly fascinating. And there may well be intelligent lifeforms on other planets able to grasp it such that to them we may as well still be living in caves. Their naturalists may run rings around ours. But that's one thing. Demonstrating the existence of an actual God revolving around an actual denomination on this planet...that's another thing altogether.Mathematics is the language of nature. But how is this to be explained? If mathematical objects like numbers and mathematical theorems are abstract entities causally isolated from the physical universe, then the applicability of mathematics is, in the words of philosopher of mathematics Mary Leng, “a happy coincidence.” On the other hand, if mathematical objects are just useful fictions, how is it that nature is written in the language of these fictions? The naturalist has no explanation for the uncanny applicability of mathematics to the physical world.
Then back to this gigantic leap:
Indeed. And if this "ready explanation" need only be believed "in your head", all the better. And if this belief comforts and consoles you by allowing you to believe in commandments on this side of the grave and immortality and salvation on the other side of it, all the better still.By contrast, the theist has a ready explanation: When God created the physical universe, He designed it in terms of the mathematical structure which He had in mind.
Right.We can summarize this argument as follows:
1. If God did not exist, the applicability of mathematics would be just a happy coincidence.
2. The applicability of mathematics is not just a happy coincidence.
3. Therefore, God exists.
