That doesn't mean God exists. But it does mean that the idea of a single God led to modern physics.
P.S. You can see this in other ways also.
Even today, we habitually talk about the "Laws of Physics". But scientists / philosophers / theologians only LOOKED for "Laws" because they already believed in a Lawgiver. They only looked for Order in the universe because they already believed it was built according to a Creator's orderly blueprints.
Really there is no rational reason whatsoever to expect the universe to be orderly at all. And certainly the universe recognizes no "Laws". Who would give those "Laws"? As an atheist, I find the idea of "Laws of Physics" utterly absurd. But it is still the way the topic is taught. And it's still the way people (including atheists) talk about the universe. As if planets "obey" some "Law of Gravity"!
Rather than see order in the world, it's much more natural to see disorder, chaos, randomness, change, flux. That's what Heraclitus saw. Indeed, the old polytheistic societies portrayed a world that was governed by arbitrary, unpredictable rivalries of various petty gods. Hence the wife of Zeus could become jealous of a mortal woman and cause the Trojan War. From such a religious background, no theologian would have spoken about an orderly universe or the eternal, irrevocable "Laws of Physics".
Instead, investigations into the supposed "Laws of Physics" or "Laws of Chemistry" occurred in monotheistic societies – first among muslims in places like Iraq, Egypt, and Iran and then (roughly 500-800 years later) among europeans in places like England and Germany. These investigations required a pre-existing belief. Unless we already EXPECT there to be laws and order, we won't look for them. At a human scale – with unpredictable wars and weather – nothing appears orderly. And an orderly, law-abiding universe would not be intuitive or expected at all.
Polytheistic and pantheistic cultures did not have reason to believe in the UNITY of the universe. Quite the contrary. They saw it as fickle, fragmentary, multifarious, strange, chaotic, and unpredictable. But monotheism – which postulated 1 single Law Giver and 1 single deliberate Creator – expected, looked for, and found exactly the opposite. Order. Laws. Unity. Predictability.
Modern science would be impossible without those expectations, which would be very unlikely without widespread monotheism.
As an atheist, I see this phase of discovery as a lucky accident, in some sense. Enlightenment-era physicists really believed they had discovered the "Laws of the Universe". Real "laws" that had been designed or prescribed by a Creator. From my perspective they were WRONG to look for laws and order. There are no laws. But they did find Order. And if any atheist DOESN'T see that Order as a mystery, then they haven't thought about it long enough. Physicists today – atheists though they may be – regard that Order as utterly mysterious, to the point of mysticism.
Primitive man would have regarded the unpredictable, chaotic world as largely unknowable. And really there is no reason to expect that any species of animal should be able to comprehend the universe with its (fictional) Laws and its (very real) Orderliness. One of the primary motivating forces for muslim scientists and later european scientists of the Renaissance and the Enlightenment was a conviction – an irrational faith – that they (a dimwitted species of ape) could discover anything and everything about the universe. Why? Because they believed the universe had been created by God, and they believed mankind had been created by God in His own image – suggesting that humans could comprehend the ways of the Creator.
And so humanity – perversely, irrationally, and unjustifiably – sought to discover what makes the world work. Because they believed that a human-like God made the world work. Without that belief, they probably would not have dared peek under the hood.
