For the official teaching of the Catholic Church on the creation of the world please read the Catechism of the Catholic Church.
The book of Genesis teaches that In the beginning God created the heavens and the earth. That is the basic message the Bible is conveying. But I think it if go over it verse by verse we will find something more.
The earth was without form and void, and darkness was upon the face of the deep(the abyss) ; and the Spirit of God was moving over the face of the water(the abyss) – before time, there was nothing but God. Darkness is the absence of light, the absence of matter.
And God said, “Let there be light”; and there was light. And God saw that the light was good; and God separated the light from the darkness…– Here we see that God created matter and a visible universe. There are some that say Genesis is wrong because light was created before the Sun, but light is a state in which all matter can exist. Also we see here God establishing an order and laws for the universe.
