It is spelled out in the Catechism. The “six days” of “creation week” are symbolical (paragraphs 337-338, also 339, 342, 345), at least some of the language of early Genesis is figurative or symbolical (paragraphs 362, 369, 375, 390, 396), the Church affirms modern science (paragraphs 159, 283-284), but Adam/Eve appear to be quite historical / literal (paragraphs 359, 375-377, 379, 388, 390-392, also 355ff on creation, and 385ff on the Fall).

Theistic Evolution vs. Six-Day Creation
If you wanna know what John Paul II thinks, he was quite clear over 20 years ago in a letter to the Pontifical Academy of Sciences on
cosmology and fundamental physics –
“Cosmogony and cosmology have always aroused great interest among peoples and religions. The Bible itself speaks to us of the origin of the universe and its make-up, not in order to provide us with a scientific treatise, but in order to state the correct relationships of man with God and with the universe. Sacred Scripture wishes simply to declare that the world was created by God, and in order to teach this truth it expresses itself in the terms of the cosmology in use at the time of the writer. The Sacred Book likewise wishes to tell men that the world was not created as the seat of the gods, as was taught by other cosmogonies and cosmologies, but was rather created for the service of man and the glory of God. Any other teaching about the origin and make-up of the universe is alien to the intentions of the Bible, which does not wish to teach how heaven was made but how one goes to heaven.” (Pope John Paul II, 10/3/1981 to the Pontifical Academy of Sciences, “Cosmology and Fundamental Physics”)
The important parts to notice here, according to John Paul II: (1) the Bible is not a scientific treatise; (2) the main point of Genesis 1 is that God is our Creator; (3) the Scripture uses the cosmology in use at the time of the writer (not a modern cosmology); (4) the Bible wishes to teach us how one goes to heaven, not how the heavens were made; (5) any other teaching about the origin and nature of the universe is alien to the intentions of the original biblical authors.
I assume you mean early Genesis (chapters 1-11), chapter 12 (Abraham) on are normally considered very historical by orthodox or conservative theologians. It’s those early chapters that scholars debate.
