Of course it states how. From the dust of the earth.
It doesn’t say that He used other animals.
When God created Eve and used Adam’s rib, He states so.
When God cursed the serpent to crawl on his belly, He states so.
How blind does one have to be to not be able to read a clearly written statement?
But if you believe that it doesn’t state how God did it, then what puts you in a position to deciding for the rest of us how God did it? Did He tell you otherwise?
That is an incomplete description. In order to comprehend what is said you need to also consider what is not said. It certainly affirms THAT God created, as was its purpose. And it even suggests the material that He used (dust was the word for the smallest particle known to ancient Hebrews. It doesn't state that it was or was not star dust, or organic dust, or moon dust, or granite dust or dust blown in from some ancient desert or dry lake bed or even pollen. It also gives no hint as to what was or was not the process used. As Pope Benedict XVI so eloquently stated;
"the Bible is not a natural science textbook, nor does it intend to be such. It is a religious book, and consequently one cannot obtain information about the natural sciences from it. One cannot get from it a scientific explanation of how the world arose; one can only glean religious experience from it. Anything else is an image and a way of describing things whose aim is to make profound realities graspable to human beings. One must distinguish between the form of portrayal and the content that is portrayed.
