“God has, in fact, written two books, not just one. Of course, we are all familiar with the first book he wrote, namely Scripture. But he has written a second book called creation.”
― Francis Bacon
When a knowledgeable person looks at a work of art, they can often tell you a great deal about the artist, even if the work is an unsigned and previously unknown piece of art. By looking at the chemical composition of the paint, and canvas they can make an educated guess when the painting was done, sometimes where it was done, if any known works by that artist have been discovered they can tell you who did it, or can identify who taught the artist, and many other things.
Genesis 1:1 In the beginning God created the heaven and the earth. (KJV)
In a sense this universe and every natural thing in it is a grand painting by God.
The same way that you can study an historical painting, and discover many things about the artist, you can study the universe and discover many things about God.
Even some atheist scientist have begun to see the need for an intelligent creator.
“All matter originates and exists only by virtue of a force which brings the particle of an atom to vibration and holds this most minute solar system of the atom together.
We must assume behind this force the existence of a conscious and intelligent mind. This mind is the matrix of all matter.”
― Max Planck
